Theres no end to the sensory stimulation and creativity with the Playfoam Mega Rainbow Pack from Learning Resources! Preschoolers can squish, squash, squeeze, and sculpt this super-satisfying, kid-safe sensory compound, then smash it down and start all over again. Child-friendly Playfoam never dries out, so the creativity never ends. Plus, Playfoam bricks blend beautifully, so kids can create their very own custom Playfoam colours. Set includes Classic Playfoam, Glow-in-the-Dark Playfoam, and Sparkle Playfoam for a totally tactile Playfoam party (32 bricks in total).
