PlayMais is a biodegradable crafting material made from corn and colored with food coloring. It is manufactured in Germany, 100% safe, and biodegradable. PlayMais stimulates children's imagination and creativity, trains fine motor skills, and develops social group skills. PlayMais can be shaped, squeezed, cut and all it takes is a little bit water to create unlimited fun. Children can build in 2 or 3 dimensions, or wherever their imagination takes them. The PlayMais XM-Box contains 250 pieces, a sponge, a biodegradable plastic knife, and an instruction booklet. It is a perfect starter box if you want to build more and bigger creations.
