It's the perfect tactile experience! You can squish it, sculpt it, mold it, roll it, cut it, save it or smoosh it and start all over again! It never dries out, is light weight and comes in multi-colors. Playfoam won't crumble or stick to skin or clothing... So requires no clean up. These remoldable sculpting beads provide that messy, tactile experience without the mess. A great beginning activity for those tactile defensive children, parents and therapists.
