Use the "magic" pen to color in the picture, and see vibrant colors, details, and patterns appear! Each of the 24 pages of these three themed kids' activity books (Fairy, Princess, and Sea Life) features artwork to complete and a seek-and-find activity, too. Invisible ink marker only marks on the pages (not clothing or furniture!) and stores in the cover, so it’s a great travel activity. This product is certified by the Forest Stewardship Council.
