The set includes 6 water coloring pages with dinosaurs and a water pen. The principle is simple: fill the pen with water and start coloring – a colorful picture gradually appears on the paper. After a short time the colors disappear, so the child can enjoy coloring again and again.
Water coloring pages are designed to be non-staining and easy to use even for younger children. If you want, instead of the water pen you can also use a brush dipped in water.
