Not ready to sell yet? Fair enough — but how you store your LEGO in the meantime directly affects what it's worth later. Yellowed white bricks and warped pieces are the two most common condition problems we see, and both are 100% preventable. Here's how to keep your collection payout-ready.
The Do's of LEGO Storage
- Keep bricks dry — moisture causes discoloration and can grow mold inside hollow studs
- Use opaque containers — direct sunlight yellows white and light-gray bricks permanently
- Choose airtight bins — they keep out dust, insects, and humidity
- Store at room temperature — stable temps preserve clutch power and shape
The Don'ts
- Don't use the attic — temperature swings and humidity are the worst combination for ABS plastic
- Don't use garbage bags — they trap moisture, tear under brick weight, and invite accidental disposal
- Don't stack heavy items on bins — sustained pressure can crack and warp pieces
- Don't store near food — crumbs attract pests, and pests love brick bins
Best Storage Containers
- 118-gallon opaque storage totes — affordable, stackable, and conveniently the same containers our payout calculator uses
- 25-gallon buckets with lids — great for large quantities and easy to carry
- 3Zip-lock bags inside boxes — perfect if you've already sorted by color or type
When You're Ready
Good storage means your bricks stay in great condition until the day you decide to sell — and that day takes about fifteen minutes of effort. Request a free shipping label whenever the bins have officially overstayed their welcome.
