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, and 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 and up.
