Coloring book with water pen for children. Coloring pad featuring Dino World designs. Five sturdy inner pages made of very thick cardboard. Printed in four colors with a magic color on the top. By moistening the pages, the designs become visible. Once dry, the images disappear again, allowing the fun of coloring to start anew. With spiral binding. The included pen can be filled with water, and by wetting the pages, the designs appear. When the paper dries, the designs vanish once more.
