The children can sort and stack forms and colours and build with the blocks. While stacking, the eye-hand coordination is stimulated and fine motor skills are trained. And as the children get older they will use it as a cradle for dolls, as fence for animals, like a tunnel or bridge for vehicles, as house for dwarfs and dollhouse dolls, build amazing sculptures... this rainbow will always be integrated in playing with a lot of fantasy. 14 pieces. Materials: lime wood, non-toxic water based color stain. Size: height 27cm. WARNING: Potential hazardous accessible points. Always put on safety cap while not assembling or disassembling wooden coloured discs.
