I bought this after buying the playset to have additional sand and tools. In hindsight, the playset came with enough tools but these are a nice addition. I am very happy with this purchase. Here is a copy of that review for the playset.Kinetic sand is strange and cool.So here's my opinion:My biggest concern was how much of a mess was this going to be. I was pleasantly surprised to find it not bad at all. It's weird because it looks like it would make your hands wet but it doesn't. I was afraid I would get all in my carpet and all over the hardwoods but it doesn't break down like sand. It stays in these little clumps that you just pick up like a piece of paper - not like sand at all like I expected. I did buy an extra bag to have more to play with since the packs that come with it isn't a lot. I will also point out that the blue and pinkish colors don't stay those colors. Within the first day after him playing with it the colors mixed together and it all became purple. I do recommend this product - lots of fun!If you found my review helpful - please click helpful found below my review and if you have questions I did not answer feel free to leave a comment or go to my profile and email me.
