Playfoam allows preschoolers to express their creativity with no mess to clean up afterward. Simply squish the Playfoam up, shape it however you like, squash it back down, & start all over again. Playfoam never dries out so the creativity never ends. The secret no-stick formula means you can take it anywhere for creative fun on-the-go. Nontoxic molding dough is recommended for children ages 3 & up.
