The book got my 5 year old son for Christmas. He paints a lot and we liked the idea of illuminated pages. The individual pages, 4 pieces of Plexiglas, can be painted with the supplied pins. The painting is a bit strange, since the color is properly visible only when the panels are illuminated and the room is dark. Nevertheless, I find painting the pins is not really good. The effect, however, is great and my little one has fun with it, and that's probably the most important thing! Cleaning is easy and can be performed by the child himself. A fun coloring book with high price !!!
