I got these for my two kids to play with because we live close to the beach. Both of them were pretty excited. I had a little trouble figuring out how to best fill them with sand, but eventually I learned to fill them piled up, close them, slide the side then shove more sand up through the bottom. The shapes are cute and the set is easy to carry with as it's lightweight. I have to admit that my kids had the most fun stomping through the sand sculptures afterwards!
