I think the Crayola Color Wonder products just aren't that good. They clame to have no mess but the paint that they have for the Color Wonder paints is actually pretty messy. You may not be able to see the mess but it leaves your childrens hands full of a greasy substance. My child actually cried because she didn't like the feel of it on her hands. I had to scrub it off her and it was slimy to wash off. We also tried the Color Wonder markers. I think they are way too expensive and the markers dry out and loose their ink way too fast. It's just not worth the money when they don't last that long....
