Discover the series that will colour to your child's world. These unique colouring books with a 'magical' water pen offer a fun and creative way to learn together. Each book includes four reusable various-themed illustrations that children can reveal — either fully or selectively — using a special water pen, without getting their hands messy. They will develop hand-eye coordination by gradually uncovering different elements: animals, plants, characters, and objects. In addition to the illustrations, these books also contain interesting descriptions with a variety of activities to help children — under the watchful eye of a parent — enrich their vocabulary, improve shape and color recognition, and practice counting, spelling, and observation skills.
