Build an amazing castle in the sand – two walls at a time! The Hape Great Castle Walls set is the perfect tool kit for kids who love to play in the sand. This set features two pieces to help you make well-defined, in penetrable walls – well, we guarantee they will be defined, but maybe not in penetrable! Both pieces are brightly colored and made from durable HDPE and ABS plastics. Build a giant sand castle with a moat, then use your molds to carry water back and fill your moat! Encourages creative play, healthy outdoor activity, and the development of fine motor skills. Durable child-safe paint finish and solid construction make this a set your child will love for years to come. Hape toys stimulate children through every stage of development and help nurture and develop their natural abilities. All Hape products sold in North America meet or exceed all applicable safety standards.
