Crayola Model Magic Variety Pack is the perfect clay-like modeling material to pass out at school or home. Soft & squishy, Model Magic is easy for young sculptors to manipulate, making it an excellent alternative to modeling clay. Use again & 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 & nontoxic, this giant set is ideal for children ages 3 & up.
