There’s no end to the sensory stimulation and creativity with the Playfoam Mega Pack! Preschoolers can squish, squash, squeeze, and sculpt this super-satisfying, kid-safe, non-toxic sensory compound, then smash it down and start all over again. Non-toxic Playfoam never dries out, so the creativity never ends. Plus, Playfoam bricks blend beautifully, so kids can create their very own custom Playfoam colors. Set includes 24 blocks of Classic Playfoam, Glow-in-the-Dark Playfoam, and Sparkle Playfoam in 10 colors for a totally tactile Playfoam party!
