Cross the texture of a crispy rice treat with the "mold-ability" of clay, and you've got PlayFoam, the lightweight foam sculpting beads that you can squish, stretch, and shape into hundreds of cool designs. It never dries out and won't stick to surfaces so use it over and over again. Plus, it's non-toxic. The classic PlayFoam six-pack includes 6 PlayFoam bricks in assorted colors. Bricks measure 2.75" W x 4" H x 1.25" D.
