Imaginative young builders can make two dimensional graphic patterns and mandalas, three dimensional towers, houses, fences, ships and so much more with this set of round and elegantly shaped blocks.

By building and playing with the Circle Flower Blocks, children develop fine motor skills and spatial thinking skills. 73 pieces in wooden frame, Ø = 40 cm , H = 4 cm
