These are the greatest invention for parents that have kids that like to draw on things other than paper. Or messy drawers that leave the paper. This has been a life saver at my house as ny daughter loves to draw but has also drawn on the walls, carpets, furniture and herself when we weren't looking. Now I can let her color without worrying. The only down side is the colors take a second to change the pages color and that if you want blank pages you have to buy the special pages that are kind of expensive.

Color Wonder products are a lot of fun for all ages!! Just beware if you put the markers away for too long they dry out more quickly then regular markers. Also, we ended up having so many books that when we went back to another book that was a bit older the papers in the books get a yellow tinge all over.
