Original Crystal Polydron CMY Class Set

96 translucent tiles in cyan, magenta and yellow — double the standard set, enough for several children to build at once or for one child to go properly big.

Rotate a cuboid in your hands and the colours shift through a spectrum. It's the kind of thing that holds attention without asking for any effort, which is worth a lot on a difficult afternoon.

Suitable from age 4. Dishwasher safe, BPA free, and comes in a sturdy reusable carton.
