This is not clay, it's foam you can sculpt - four stars only cause it's misleading

This is a good set of foam that you can mold into things. I got it for my kids and 23 of the colours were great, the black was solid foam (unsculptable) as the lid was off.  At first I didn't really like it as the foam had a texture to it, but the trick is that you need to work it in your hands for awhile and it becomes smooth and really easy to work with and doesn't look bumpy etc.  

My kids have had a lot of fun playing with this and have made a ton with it.  Highly recommend but they should change the packaging to note that it is foam not clay, methinks it's probably something that was lost in translation.
