Inspired by the Japanese game "tumi ishi", an ancient Japanese rock piling game, our stacking rainbow rocks improve concentration and creativity.
Stacking them is not easy and is even fun for adults to try.
This 36 piece set can be used for:
- Easter egg hunts
- Colour sorting
- Stacking sets of two
- Arranging by colour into a proper rainbow
The colours/rocks will differ between each set. No two sets are exactly the same.
