We buy your unused LEGO® bricks for cash — quickly and reliably  

If you no longer need your mixed LEGO bricks or sets, we buy them, pay you quickly, refurbish complete sets from them, and put them back into the hands of a new generation of builders.

Why do we need your bricks?

Most children receive new LEGO sets twice a year — for Christmas and on their birthday. Few families can afford to buy them more often.

Meanwhile, millions of boxes with mixed bricks pile up at homes around the world — too good to throw away, but too difficult to sort and reuse.

That’s why we’re building an AI-powered automated brick-sorting system that makes brick play more affordable, sustainable, and fun.

The used bricks you sell us are not only turned into ready-to-build sets and brought back into play — they also help us improve our sorting technology for the next generation of builders.

How does selling bricks work?

1

Fill out the form

Leave your details, your country and the approximate weight of your bricks. When it's your turn, we'll send you an invitation to book a shipping week.

2

Send your bricks

Book your shipping week, and we’ll email you a free shipping label before your shipping day. Pack the bricks securely, attach the label, and ship them to us via home pickup or your nearest DHL location.

3

Get paid

Once we get your bricks, we weigh them and pay you 50% of the estimated amount. After inventorying and matching them to restorable sets, we pay the balance based on the actual weight of genuine LEGO parts and minifigures.

What we buy — and what we don't

Send these

We buy: Regular LEGO® and LEGO® Technic sets, regardless of theme or year.

Don't send

We don’t buy: DUPLO®, MODULEX, or sets from other construction toy brands.

Please send your whole collection in one go — the more complete it is, the more accurately we can recognise the sets and value your bricks. 

Brick Selling Calculator

kg
A shoebox full of bricks ≈ 2 kg. Use it as a reference.
Estimated LEGO® bricks 0.00 kg
Estimated LEGO® minifigures* ~0.00 kg

*Based on past orders, minifigures typically account for around 2% of a collection’s weight. This is already factored into the estimate. Minifigures are valued separately at much higher price per kg, so send them all.

Your Payout Estimate

Estimated LEGO® bricks (€8/kg × 0.00 kg) €0.00
Estimated LEGO® minifigures (€50/kg × ~0.00 kg) €0.00
Estimated payout €0.00
This is an estimate only. Your final payout will be based on the verified weight of genuine LEGO® bricks and minifigures we receive.

Not sure? A shoebox is about 2 kg.
