Mystery Box
Description
Presenting the PowerBuild® Mystery Box — a monthly subscription that delivers a brand‑new PowerBuild® product to your door, every month.
Here's how it works: you pay monthly, and on the same date each month you'll receive a different PowerBuild® set. The contents are 100% random and can include anything from our entire catalogue — cars, off‑roaders, trucks, engines, collabs, special editions and more.
No repeats. Every month is a new surprise, with a new model — never the same box twice.
And here’s the best part: you may receive early access products — including sets that haven't launched yet and are not available for purchase on the store.
If you love the thrill of collecting and discovering what’s next, the PowerBuild® Mystery Box is the easiest way to build your lineup month after month.

Mystery Box Specifications
Bricks Quality
PowerBuild® sets are engineered for an exceptionally smooth building experience. Each brick clicks firmly into place with a precise fit that feels both solid and satisfying. Once assembled, the structure holds strong, yet an included brick separator tool allows you to easily adjust or rebuild whenever you like. To enhance authenticity, certain elements feature chrome, gold or metallic finishes, adding a distinctive touch that makes every model stand out.
Who designed this model?
This model, like many others from PowerBuild®, was designed by MoonRock — one of the creative minds behind our most iconic builds.
