Crayola Model Magic Variety Pack is the perfect clay-like modeling material to pass out at school or home. Soft and squishy, Model Magic is easy for young sculptors to manipulate, making it an excellent alternative to modeling clay. Use again and again if kept in a resealable plastic bag, or children can make their creations permanent by letting them air dry overnight. Each of the 30 individually wrapped packs of Model Magic comes in 1 oz. sealed pouches. Safe and nontoxic, this giant set is ideal for children ages 3 and up.
