With the Aqua Magic book in Ylvi design, you are guaranteed a lot of colouring and crafting fun. On the 5 fixed pages in white, detailed patterns are hidden which become visible when in contact with water and disappear after drying. In addition, the kit includes a refillable water pen that allows painting the inside with water again and again. The high-quality colouring book can be easily rotated thanks to the practical ring binding and measures approximately 19 x 18 x 2 cm..
