This is a very fun game and easy to handle. I had initially taken for my second 2-year, which enjoyed but especially the first 5 years who preferred. Less messy than clay, creation is up to the imagination. The balls can be cut, crushed, rolled and finally glued (just moistening them on a wet paper which is supplied) to give them the desired shape. The dye is not health food risk and easy to remove on surfaces. BUT be careful if you live in a tropical country because after six months in the small cardboard box I was shocked to discover a nest of cockroaches, certainly because of product composition (based on cereal) but it is an exceptional case.
