This playsand and mold kit is so much fun.. Not only did it come with it's own 4 pounds of sand and 45 oieces of sand mold, and 1 tray, it can be used in regular sand at the each. Who knows maybe my grand kids will become the next sand artists! The sand that comes with the kit is a special sand, made with beeswax to make it mold easier. The tray is blow up so it is easy to store. this is a perfect out doors activity for the kids now that the weather is better. Fun and easy for them to use! the molds are safe and non toxic, easy to use and don't have any sharp edges, so they are safe even for little hands. Overall this is a great and fun kit!
