Kids can open the case and unleash endless free-flowing creativity as they mold, shape, and squish the teal sensory sand into incredible sand art or anything they can imagine! The Castle Case is designed to lay flat and keeps the sand contained for hours of open-ended play. The One and Only Kinetic Sand is made from natural sand that sticks to itself for easy cleanup! It never dries out, so you can create again and again. Let it flow through your hands its so satisfying, you wont be able to put it down! After play, the Castle Case folds back up for convenient storage and easy cleanup until next time. Kinetic Sand is an exciting alternative to arts and crafts modeling clay and is a welcome addition to the craft table, sensory bin, kids activities time and Montessori toys. Kinetic Sand promotes fine motor skills and creativity in kids aged 3 and up through independent tactile play.
