Shape, build and sculpt! Classroom activities just got more fun with 12 colors of Crayola Modeling Clay included in this Crayola Classpack Set. This 24 piece kit of clay for kids, gives little artists everything they need to mold soft sculptures with a variety of colors that will inspire them to create in 3D. This versatile, non-hardening clay is completely reusable. It even stays soft after molding, ensuring it can keep up with your child's imagination. The clay also resists water thanks to its wax and oil-based formula, further lengthening its lifespan. Clay sculptures of animals, cartoons, people and outdoor scenes are just the beginning of what kids can create with this non-hardening, reusable clay. Crayola modeling material is a stable for classroom projects, school assignments, and at home arts and crafts. Makes a great gift for teachers and kids ages 4 and up.
