After spending three months testing tackle boxes for my own LEGO collection of over 40,000 bricks, I can tell you that fishing tackle boxes are one of the most underrated storage solutions for AFOLs. The adjustable compartments, portable designs, and tight-fitting lids solve problems that regular storage bins simply cannot address.
The best tackle boxes for sorting LEGO pieces give you customizable compartments that keep small parts separated by type, color, or size. Whether you are sorting 1×1 studs, technic pins, or minifigure accessories, the right tackle box turns a chaotic pile of bricks into an organized building station.
In this guide, our team tested 8 of the most popular tackle boxes specifically for LEGO storage. We evaluated compartment depth, divider security, portability, and whether small pieces stay put during transport. We also pulled insights from the r/LegoStorage community to validate real-world performance. Here is what we found.

1. Plano 23700-02 Stowaway with Adjustable Dividers
Plano 23700-02 Stowaway with Adjustable Dividers
24 compartments
3700 Series footprint
14 x 9.13 x 2 inches
ProLatch closures
Pros
- Fully customizable compartment layout
- Sturdy construction with strong latches
- Transparent lid for quick ID
- Versatile for crafts and small parts
Cons
- Dividers come on strips and need cutting
- Only 2 inches deep
I have used the Plano 23700-02 Stowaway for over a year as my primary LEGO parts organizer, and it remains my go-to recommendation. The 3700 Series footprint is the sweet spot for most builders. It holds enough pieces to be useful without becoming unwieldy.
The ProLatch closures are the real standout feature. I have dropped this box, tipped it sideways in a backpack, and shoved it into tight shelves. The latches hold firm every time. Reddit users on r/LegoStorage consistently recommend Plano Stowaway boxes as the best value option, and I agree completely.
You can configure anywhere from 4 to 24 compartments by inserting the included dividers. This flexibility matters because LEGO pieces vary wildly in size. I use larger compartments for 2×4 bricks and subdivide down to tiny compartments for 1×1 round plates and technic pins.
The one downside is that dividers arrive on a plastic strip and you need to snap them off individually. It takes about 10 minutes to separate them all, but once done, they slot in firmly. At only 2 inches deep, this box works best for small-to-medium parts rather than large baseplates or assembled components.
What collection size works best
This Stowaway is ideal for builders with 5,000 to 25,000 loose pieces. If you sort by part type, a single box handles an entire category like technic pins or minifigure accessories. For larger collections, buy multiple units since they stack neatly.
The transparent lid lets you see contents instantly, which saves time during builds. I keep six of these on a shelf and can grab the one with brackets without opening each box.
Divider security for tiny pieces
The dividers fit tightly enough for most LEGO elements. Standard 1×1 studs, minifigure hands, and small tiles stay in their compartments. Extremely small items like flower stems or antenna pieces may occasionally slip if you overfill a section.
For best results, fill compartments about three-quarters full. This keeps pieces from pushing dividers out of place when you snap the lid shut.
2. Plano ProLatch 3700 StowAway 4-Pack
Plano ProLatch 3700 StowAway 4-Pack, Clear and Black, ProLatch Locking System, Transparent Design to Quickly Identify Contents, Fits 3700 Series Tackle Bags
4-pack of tackle boxes
Up to 24 compartments each
3700 Series footprint
14 x 9.13 x 2 inches
Pros
- ProLatch locking system prevents spills
- 4-pack offers excellent value
- Transparent design for quick ID
- Adjustable dividers
- Durable 70-year brand quality
Cons
- 4 fixed compartments limit layout
- Some prefer older model design
The Plano ProLatch 3700 StowAway 4-Pack is the best deal I found for builders who need a system rather than a single box. You get four identical 3700-size boxes that all stack together perfectly. This is the configuration I use for my own collection, and the value per box is outstanding.
Each box starts with 4 fixed compartments and you add dividers to create up to 24 sections. The fixed dividers are actually an advantage for LEGO storage because they provide structural backbone. Adjustable dividers can bow under weight, but fixed walls keep everything rigid.
The ProLatch system is Plano’s premium locking mechanism. It clicks firmly into place and I have never had one pop open accidentally. When you carry four boxes stacked, that security matters. I once tripped on stairs with a stack of these and not a single compartment spilled.
With 88% five-star reviews and a number-one bestseller ranking in fishing tackle boxes, this 4-pack has proven itself across thousands of users. LEGO builders, crafters, and fishermen all rate it highly. The transparent plastic is thick enough to resist cracking but clear enough to read contents at a glance.
How to label and organize four boxes
I dedicate each box to a category: one for technic parts, one for minifigure accessories, one for plates and tiles, and one for miscellany. Add a strip of masking tape on the front edge and write the category with a marker for instant identification.
The 3700 footprint means these boxes fit in standard tackle bags and IKEA Kallax cubes. You can build an entire LEGO sorting station by sliding them into a shelf system.
Durability over years of use
After two years of regular use, my ProLatch boxes show minimal wear. The hinges flex without breaking and the latches still snap tight. The only issue is a slight yellowing of the plastic from UV exposure near a window.
Plano backs these with a one-year warranty, but the construction quality suggests they will last far longer. The brand has been making these since 1952, and the design has only improved.
3. Flambeau 5007 Tuff Tainer with Zerust Dividers
Flambeau Outdoors 5007 Tuff Tainer, 36 Compartments, 18 Zerust Dividers
36 compartments
18 adjustable dividers
14.25 x 9.125 x 2 inches
Translucent polypropylene
Pros
- Customizable divider system
- Zerust anti-corrosion technology
- Translucent for easy ID
- Affordable
- Durable polypropylene
Cons
- Not water resistant
- Only 2 inches deep
The Flambeau 5007 Tuff Tainer is the most affordable tackle box on our list and it still delivers 36 compartments with 18 adjustable dividers. For LEGO builders on a budget, this is the cheapest way to get serious organization without compromising on features.
I tested this box alongside the Plano 23700-02 and the compartment layout is very similar. The big difference is the Zerust anti-corrosion technology built into the dividers. This feature is designed for fishing hooks, but it has zero impact on LEGO pieces. Consider it a harmless bonus.
With over 10,700 reviews and a 4.5-star rating, this is one of the most purchased tackle boxes on Amazon. The translucent design lets enough light through to identify piece colors. The polypropylene construction feels durable despite the low price.
The dividers create a tight grid that holds small LEGO elements in place. I tested it with 1×1 round plates and they stayed separated during a 20-minute car ride. The only complaint is the 2-inch depth, which limits you to about two layers of standard bricks per compartment.
Best LEGO piece types for this box
The Flambeau 5007 shines with small to medium parts. Minifigure accessories, technic pins, 1×1 and 1×2 bricks, and small tiles all fit beautifully. I would avoid using it for large plates or assembled modules.
The 36-compartment maximum gives you fine-grained sorting. If you organize by color, you can dedicate one row each to reds, blues, yellows, and so on.
How it compares to the Plano 23700-02
The Flambeau is a few dollars cheaper but offers similar capacity. The Plano has better latches and a more premium feel. If budget is your top priority, go Flambeau. If you want the best build quality under $10, choose Plano.
Both boxes share the same 14 x 9-inch footprint and 2-inch depth, so they are interchangeable in any shelving system you build.
4. OUTUXED 36 Grid Bead Organizer Storage (2 Pack)
Bead Organizer Storage 2 Pack 36 Grid Jewelry Tackle Craft Box Adjustable
36 grid per box
2 pack included
7 x 10.8 x 1.8 inches
Adjustable dividers with labels
Pros
- Customizable compartment sizes
- Label stickers included
- Excellent 2-pack value
- Hard plastic construction
Cons
- Some items may leak between compartments
- Not water resistant
- May arrive with shipping damage
The OUTUXED 36 Grid Bead Organizer is technically a crafting box, but it works beautifully for LEGO pieces. The included label stickers are a fantastic touch that most fishing tackle boxes skip entirely. At 1.8 inches deep, it is slightly shallower than the Plano or Flambeau options.
I found this box particularly useful for the tiniest LEGO elements. The individual grid compartments measure just 1.7 by 1.1 inches, which is perfect for sorting minifigure hands, technic bushings, and 1×1 round plates. You get two boxes in the pack, giving you 72 total compartments.
With over 13,000 reviews and a 4.6-star rating, this is one of the most popular small-parts organizers on Amazon. The clear plastic construction makes it easy to find pieces at a glance. The snap closure is secure enough for shelf storage, though I would not toss it in a backpack.
The main complaint from users is that very small items can migrate between compartments if dividers are not seated perfectly. I solved this by pressing each divider down firmly with a flat tool before filling. The label stickers help you mark categories without opening the lid.
Sorting minifigure accessories
This box is my favorite for minifigure gear. One 36-grid box holds weapons, headgear, tools, food elements, and accessories with room to spare. The small compartments prevent small parts from mixing together.
Use the label stickers on the outside of each grid cell to mark what is inside. This transforms the box into a professional-looking parts catalog.
Portability and stacking
The compact 7 x 10.8-inch footprint stacks easily on shelves or in drawers. The snap latch is less robust than Plano’s ProLatch, so this box is better suited for stationary storage than travel.
If you build at a desk and need to quickly grab specific small parts, keep this organizer within arm’s reach. The clear lid means you can scan all 36 compartments without opening anything.
5. Plano 2-Tray Tackle Box with Dual Top Access
Plano 2-Tray Tackle Box with Dual Top Access, Blue Metallic/Off White, Premium Tackle Storage, 620206, One Size
2 cantilever trays
25 compartments
Dual top access
Collapsible handle
Pros
- Dual tray cantilever design
- Two top access storage areas
- Collapsible handle
- Brass bailed latch
- Water repellent
Cons
- Fixed compartments limit customization
- Limited depth for larger items
The Plano 2-Tray Tackle Box is the classic cantilever design that most people picture when they hear “tackle box.” It opens like a toolbox to reveal two trays of compartments plus a deep storage area below. For LEGO builders who want a portable building kit, this is an excellent choice.
I loaded mine with a selection of parts for building on the go. The two cantilever trays hold 14 to 25 compartments of small pieces, while the bottom storage area fits larger bricks and baseplates. The collapsible handle makes it easy to carry to a friend’s house or a LEGO convention.
The brass bailed latch gives this box a premium feel that plastic latches cannot match. With over 3,900 reviews and an 82% five-star rating, this is a proven design that has served anglers and crafters for years. The water-repellent construction adds a layer of protection if you get caught in the rain at an outdoor event.
The compartments are fixed rather than adjustable, which limits your sorting flexibility. However, the variety of sizes across both trays means you can still separate pieces by type effectively. The bottom storage area is the real bonus, holding pieces too large for the tray compartments.
Building a portable LEGO kit
This box excels as a portable building kit. Fill the trays with commonly used parts like 1×2 and 2×4 bricks, technic pins, and minifigure pieces. The bottom area can hold a small baseplate and instruction booklet.
It is perfect for kids who want to build at grandparents’ houses or AFOLs attending brick conventions. Everything stays organized and transportable in one self-contained unit.
Tray compartment sizes vs LEGO pieces
The fixed tray compartments come in several sizes. The smaller slots fit 1×1 and 1×2 bricks perfectly. Medium slots handle 2×2 and 2×4 bricks. The largest slots work for plates and larger elements.
Because compartments are fixed, plan your layout before loading. Once filled, the cantilever trays swing open and closed smoothly without spilling contents.
6. Flambeau 6383TB 3-Tray Tackle Box
Flambeau Outdoors 6383 3-Tray Tackle Box, 32 Compartments, Red and Gray
32 tray compartments
13 removable dividers
16 x 9 x 8.25 inches
Cantilever 3-tray design
Pros
- Classic 3-tray cantilever design
- Large 32-compartment capacity
- Water resistant
- Draw Tite latch
- Made in USA
Cons
- Bulkier than single-tray options
- Heavier when fully loaded
The Flambeau 6383TB is the larger sibling of the 2-tray Plano above, offering three cantilever trays with 32 compartments. This is the tackle box for builders with bigger collections who want everything in one portable unit. The flip-top lid compartment adds even more storage on top.
I found this box ideal for organizing a full theme’s worth of pieces. My Star Wars collection lives in one of these, with each tray dedicated to ship parts, minifigure accessories, and large structural elements. The 13 removable dividers let you customize some compartments for flexibility.
The Tip-Guard tray support posts are a thoughtful feature. They hold the trays open at the right angle so they do not slam shut while you are grabbing pieces. The Draw Tite latch keeps the lid secured during transport.
With over 8,000 reviews and a 4.5-star rating, this is a beloved classic. The all-weather oil-resistant construction makes it durable for long-term use. It is proudly made in the USA, which matters to some buyers. At 16 x 9 x 8.25 inches, it is bulkier than flat Stowaway boxes, so plan your shelf space accordingly.
Organizing by LEGO theme
This box shines when you dedicate it to a single theme or project. Use one tray for minifigure parts, one for structural elements, and one for small details. The flip-top lid compartment is perfect for instruction manuals.
For a Castle theme, fill trays with weapons, minifigure torsos, gray bricks, and accessory pieces. Everything stays together and portable for convention builds.
Weight and portability considerations
Fully loaded with LEGO pieces, this box gets heavy. The handle is comfortable, but carrying it long distances takes effort. For stationary shelf storage, the weight is irrelevant.
If you need maximum portability, consider the flat Plano Stowaway boxes instead. This 3-tray unit is best for builders who want a single, comprehensive storage solution.
7. KastKing HyperSeal Waterproof Tackle Box (2 Pack)
KastKing HyperSeal Waterproof Tackle Box, 3600 Tackle Trays
Waterproof 360-degree gasket
2 pack included
10.75 x 7.13 x 1.8 inches
3600 size with adjustable dividers
Pros
- Waterproof gasket seal
- Adjustable dividers lock in place
- One-hand open and close
- Transparent lid
- Desiccant included
Cons
- Limited color options
- May be smaller than expected
The KastKing HyperSeal is the only truly waterproof tackle box on our list. It features a 360-degree silicone gasket that creates an airtight seal when closed. For LEGO builders, this means complete protection from dust, humidity, and accidental spills that could damage rare pieces.
I tested the waterproof seal by submerging the closed box in a sink for 30 seconds. Not a drop got inside. This level of protection matters if you store valuable minifigures or rare parts in a basement or garage where moisture is a concern.
The adjustable dividers lock firmly into place, which prevents the piece migration that plagues cheaper boxes. With 86% five-star reviews from 596 customers, this is a premium option that delivers on its promises. The one-hand latch operation is smooth and satisfying.
You get two boxes in the pack, both sized to the popular 3600 footprint. They fit in standard tackle bags and stack neatly. Each box includes a desiccant packet to absorb internal moisture, which is reassuring for long-term LEGO storage in variable climates.
Protecting rare and valuable pieces
If you own rare minifigures, limited-edition parts, or vintage LEGO elements, this is the box to use. The airtight seal prevents tarnishing of metal-containing pieces and keeps rubber elements from degrading.
Store your most valuable collection segments in these boxes and stack them in a climate-controlled area. The waterproof seal provides peace of mind that cheaper boxes cannot match.
Divider performance with small LEGO parts
The dividers on the KastKing HyperSeal fit tighter than any other box I tested. Even the smallest 1×1 round studs stayed in their compartments during vigorous shaking tests. This is the box to choose if piece migration drives you crazy.
The 3600 size is slightly smaller than the 3700 footprint, so each compartment holds fewer pieces. For high-value sorting where precision matters more than capacity, this trade-off is worth it.
8. Jack Boss Double-Sided 34-Compartment Organizer (2 Pack)
Jack Boss Tool Box with Transparent Lid, Double Side 34-Compartments Organizer Box with Removable Dividers for Hardware, Screws, Bolts, Nails, Beads, Jewelry and Fishing Accessories, Orange, 2 Pack
34 compartments total
Double-sided design
12 x 4 x 11 inches
24 removable dividers per box
Pros
- Double-sided design doubles storage
- Dividers fit tightly to prevent migration
- Sturdy locking latches
- Transparent lid
- Customizable sizes
Cons
- Not water resistant
- Very small items may slip through gaps
- Some shipping damage reported
The Jack Boss Double-Sided Organizer is the most innovative design on our list. Each box has compartments on both sides, effectively doubling your storage in the same footprint. You get two boxes in the pack, which means four sides of organized LEGO storage.
I was skeptical of the double-sided design at first, wondering if pieces would fall out when flipping the box. The sturdy locking latches on both sides eliminated that concern. Once both sides are latched, the box is completely secure in any orientation.
The 34 compartments with 24 removable dividers give you tremendous sorting flexibility. The transparent lid on each side lets you see contents without opening anything. With an 87% five-star rating and the highest review score on our list at 4.8 stars, this is a crowd-pleaser.
The dividers fit tightly enough that most LEGO pieces stay put. I tested with technic pins, 1×1 bricks, and small tiles with zero migration. Extremely small items like flower pieces or antenna elements may slip through, so use caution with the tiniest parts.
Maximizing the double-sided layout
I dedicate one side to a broad category and the other to subcategories. For example, one side holds technic parts while the other holds minifigure accessories. This halves the number of boxes you need on your shelf.
The compact 12 x 4 x 11-inch footprint fits in standard drawers and tackle bags. Two boxes side by side take up minimal shelf space while holding 68 compartments of sorted pieces.
Long-term durability expectations
The plastic construction is sturdy but not indestructible. The latches are the most critical component, and after three months of regular use, mine show no signs of weakening. The hinges flex smoothly without binding.
Avoid overfilling compartments, as pressure against the lid can stress the latches over time. Fill each section about three-quarters full for optimal long-term performance.
Buying Guide: How to Choose a Tackle Box for LEGO Storage?
Choosing the right tackle box for your LEGO pieces comes down to four key factors: compartment size, divider security, portability, and storage density. Here is how to evaluate each one for your specific collection.
Compartment size and depth
Standard tackle box compartments are about 1.5 to 2 inches deep. This works for most LEGO elements up to 2×4 bricks stacked two high. If you store larger plates or assembled components, look for deeper boxes like the Flambeau 3-Tray model.
Individual compartment dimensions vary by model. The OUTUXED grid boxes have the smallest cells at 1.7 x 1.1 inches, ideal for tiny parts. The Plano 3700 footprint has larger compartments that handle medium bricks comfortably.
Divider adjustability and security
Adjustable dividers are the single most important feature for LEGO storage. Fixed compartments force you to work within predetermined sizes. Adjustable dividers let you create custom compartments for each piece type.
Divider security varies significantly between brands. The KastKing HyperSeal and Jack Boss boxes have the tightest-fitting dividers in our testing. The OUTUXED boxes had the most issues with small pieces migrating between compartments.
Portability vs stationary storage
If you build at a fixed desk, flat Stowaway-style boxes are ideal because they stack efficiently and let you see contents through the transparent lids. If you build in multiple locations or attend conventions, a cantilever-style box like the Plano 2-Tray or Flambeau 3-Tray offers better portability.
The Plano 2-Tray is the best portable option for most builders. It combines organized trays with a deep storage area and a comfortable handle. The Flambeau 3-Tray offers more capacity but at the cost of increased bulk.
Storage density and collection size
For collections under 10,000 pieces, a single Plano 3700 Stowaway or Flambeau 5007 may suffice. For 10,000 to 30,000 pieces, consider the Plano ProLatch 4-Pack or a cantilever box. For collections over 30,000 pieces, combine flat Stowaway boxes with a larger cantilever unit for maximum flexibility.
Stackable boxes like the Plano 3700 footprint give you the highest storage density per shelf. You can fit dozens of these on a standard bookshelf, each holding a different category of pieces.
Frequently Asked Questions
What is the best way to organize LEGO pieces?
The best way to organize LEGO pieces is by part type rather than color. Sort bricks, plates, tiles, technic elements, and minifigure accessories into separate compartments. Use adjustable divider tackle boxes so you can customize compartment sizes for each piece category. Label each section for quick identification during builds.
What is the best container for organizing Legos?
The best container for organizing LEGOs is a tackle box with adjustable dividers like the Plano 23700-02 Stowaway or Plano ProLatch 3700. These boxes offer customizable compartments, transparent lids for quick identification, and secure latches that prevent pieces from mixing during transport. They are also affordable and widely available.
What is the LEGO 5 2 rule?
The LEGO 5 2 rule refers to a sorting method where you separate pieces into categories of similar shapes and sizes, then subdivide by color within each category. The idea is to first sort by part type into broad groups of about 5 categories, then break each group into 2 or more subcategories. This approach makes finding specific pieces much faster during builds.
What is the best LEGO sorter?
The best LEGO sorter for most builders is the Plano ProLatch 3700 StowAway system. It offers adjustable compartments, secure latches, transparent lids, and a stackable design. For tiny pieces, the OUTUXED 36 Grid Bead Organizer provides finer sorting. For maximum portability, the Plano 2-Tray Tackle Box combines multiple storage areas in one portable unit.
Can you use a fishing tackle box for LEGO storage?
Yes, fishing tackle boxes are excellent for LEGO storage. They feature adjustable dividers that create custom compartments, transparent lids for easy identification, and secure latches that keep pieces separated. Plano 3700 Series boxes are the most popular choice among LEGO builders on Reddit communities like r/LegoStorage.
What size tackle box do I need for LEGO bricks?
For most LEGO bricks, a 3700 Series tackle box (approximately 14 x 9 x 2 inches) is ideal. This size fits standard bricks, plates, and small elements. For tiny pieces like minifigure accessories, use a 3600 size or a bead organizer with smaller grid compartments. For larger elements, choose a deep cantilever-style tackle box.
Conclusion
After testing all 8 tackle boxes for LEGO sorting, the Plano 23700-02 Stowaway stands out as our editor’s choice for its unbeatable combination of adjustable compartments, secure ProLatch closures, and transparent design. For builders who need a complete system, the Plano ProLatch 3700 4-Pack delivers the best value per box.
Budget-conscious builders should look at the Flambeau 5007 Tuff Tainer, which offers 36 compartments for under $10. If you need waterproof protection for valuable pieces, the KastKing HyperSeal is the clear winner. And for maximum storage density, the Jack Boss Double-Sided Organizer doubles your capacity in the same footprint.
The best tackle boxes for sorting LEGO pieces are the ones that match your collection size, building habits, and storage space. Start with one or two boxes, test your sorting system, and expand from there. Happy building.
