clay is fun, very light & foamy. It dries quickly so do one item at a time. luckily the kits come with glue so pieces that dry too quickly may still be added. The colors mix well to make additional hues. I wish a double of portion of white were included as many of the projects use grey but no grey is included so we ended up using alternate colors so as not to waste the white.
downside - Only a small portion of clay of each color is included. Animals are the size of the tiny eraser animals that are popular right now.
My daughter is 9, she enjoyed it very much!
