Lightweight modeling clay is specially designed for children's fingers, making it easy to mold. Its feature is that after drying, the mass completely hardens and retains the shape of the figure. This type of clay does not stain clothes, hands,... or furniture, does not crumble, and does not sink in water! Colors can be mixed together to create new shades. Sculpting with air-drying clay develops fine motor skills, coordination, creativity, and imagination. The set contains 48 colors of 13g each.
