《Dinosaurs》 This is a fascinating educational coloring book that you can play with using only water. No paint or crayons are needed; simply fill the included special water pen with water and trace the pictures in the book to reveal colorful images. I have opened and used it once. The contents have been completely dried. The box is as shown in image 5. The colors disappear when air-dried, allowing for repeated use. There's no need to worry about staining clothes or floors, making it convenient for playing at home, on the go, during travel, or anywhere. The material is soft and designed with no sharp corners for safety. It's a compact size of 15x15cm, easy for young children to handle, and is recommended as an educational toy to train fine motor skills, improve concentration, and foster imagination. 【Types (※Many other types are also available)】 ・Sea Creatures (octopus, fish, etc.) ・Princesses ・Vehicles (cars, trains, airplanes) ・Dinosaurs Bundling is possible.
