Mystery Box specifications

How does the Mystery Box work?

You subscribe monthly and receive a different PowerBuild® set on the same date each month. The contents are 100% random and can include anything from the full catalogue — cars, engines, off-roaders, collabs, special editions and more.

Will I ever receive the same set twice?

Never. Before every shipment we check your full order history to make sure you receive a model you haven't gotten before.

Can I receive sets that aren't available in the store yet?

Yes. Mystery Box subscribers may receive early access products — sets that haven't launched yet and are not available for purchase anywhere else.

What arrives in the box?

You receive the random PowerBuild® set in its original collector's packaging, including its instruction manual — and if the model includes a Display Box Container, yours will include it too. Every set ships complete, exactly as it was designed.
