The new classroom pack is perfect for a store demo, classroom project or kids’ party. Each classroom pack includes ten 11-Ounce packages of our special air-dry clay, ten plastic molds, and a set of alphabet and number stamps to share. The white, non-toxic, air-dry clay featured in our Classroom Handprint Kit is simple to use – no mixing or baking. Just mold it, create your impression, and allow several hours to dry. Clean up with soap and water.
