My daughter received this as a gift and was delighted with it, however, found it hard to mould. The greasy film it leaves on hands is unpleasant. The dough itself does not mould easily and reminds one more of used chewing gum than a craft product. And honestly, one might get more product if one used chewing gum!
Left to set overnight, the pieces my daughter made with my help were soft and slimy as though they had never been set. This from a product that says it sets in 30 minutes to an hour.
Horrible, horrible stuff and I just KNOW she won't let me throw it out!
