Lightweight and spongy, even after drying. This unique modeling material is fun to use and easier to shape than regular clay. The non-crumbling formula sticks to itself but not to your hands! Now store model magic to stay soft longer, while finished projects can be left out to air dry. Use Crayola markers, paints or other decorative items to embellish your designs. Package contains: 3 colors (2.25oz/63g). Non-toxic. Conforms to ASTM D4236. Not for children under 3 years. Made in the USA.
