It easily molds and never dries out, so you can build again and again. Use the 6 castle-themed molds to build your sandcastles and create towers, walls, bridges and more. The 2 multi-use tools can be used to cut, dig, rake and shovel your kinetic beach sand! Unfold the box to reveal a beachy play space and create sandcastles anywhere. When you’re finished building sandcastles for the day, clean-up is easy. Gather your kinetic beach sand into a large ball and use it to pick up smaller bits of sand, then pack everything away into the box until next time.
