DO NOT WASTE YOUR MONEY ON THIS PRODUCT
Bought two sets, one for my house and one for my grand kids. This product is horrible. Because of the name recognition I assumed it would be fun in the tub.  When the children squeezes the tube the paint gushed out and leaked in the bath water and all over everything the children. It was a mess to clean up. My daughter in law immediately threw these pens in the garbage and so did I when I tried them. What a waste of money and what a mess!!! I wish I had taken pictures to show you how messy it really was.
