What is a Mystery Box?

A Mystery Box is a package where the contents are a secret – you won’t know exactly what you get until you open the box. It’s like receiving a gift, but without knowing what’s inside. The colors and themes vary, and each box contains a selection of Plus-Plus products, perfect for creative play and exploration. You might find the latest colors, fun themes, or rare versions that you can’t find anywhere else. Every box is a new chance to discover something amazing.

Unleash your imagination – and let yourself be surprised by what your Mystery Box has in store.

More pieces = more play… and more surprises. Each Mystery Box hides a colorful and imaginative surprise – maybe wheels, baseplates, or glitter colors. Every single box is filled with creative potential.

You can also choose between two other sizes, Medium and Large
