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.
In our house, the little ones use them for:
- Easter egg hunts
- Colour sorting
- Stacking sets of two
- Arranging by colour into a proper rainbow
Choose between 12 pieces or 36 pieces. The 36 pc "multi-color" is a mixture of the blue and pink hues in the 12 pc sets. The colors/rocks will differ between each set. No two sets are exactly the same.
