This is a good variety set for smaller kids in a smaller pop up pool. They seem to be made of a lighter plastic and not a super durable kind. Some of the gems are only one sided and hollow so they lay pretty flat, so I wouldn't use in a deeper pool - so maybe keep away from smaller ones that like to put things in their mouths. Overall, these are super fun!
