Sands Alive! is 100% non-toxic, anti-bacterial and won't stain. Picks up easily off floors and carpets. Mold it into hard durable shapes, and with a soft touch, it will break apart and appear to move, almost as if it were alive! This wonderful play set comes with 1.5 pounds of Sand, a Paver Vehicle with 2 replaceable Rollers (in Rock Crush and Smooth designs), and the Backhoe has a repositionable Scooper.
