Bought for my son under 2 years. The die parts used primarily for salt dough for the moment. We use the forms that best clean (ie no corners where dough remain stuck). He loves, knows to use them now and pick them up for itself when preparing the activity. We rarely shortbread with but it works as well :-) By cons, as in previous reviews, the box is very big and has many rooms. The third would have been enough!
