Playing with squeezy sand is an activity that children love and helps them develop multiple skills. The craft kit includes a plastic container for building, three molds, four bags of sand, two craft tools and a roller. Everything you need to build your own glittery castle! The sand retains its shape until you want to build something else. The sand doesn't dry out or get wet so it's perfect for mess-free fun. Tip: play in the container as much as possible so that it is easy to clean up. The colors of the sand can vary.
