This is a children's educational drawing toy: a reusable water painting notebook featuring vibrant dinosaur illustrations (purple long-necked sauropod, pink small dinosaur, red flying pterosaur) in a prehistoric landscape. The notebook uses special water-activated paper that reveals colors when painted with a water brush—no ink or mess. The spiral-bound design allows easy page turning, and the 'non-staining clothes' claim ensures safe use for kids. Text in Chinese highlights key features: '清水作画' (water painting), '可重复使用' (reusable), and '不脏衣物' (won't stain clothes). Ideal for developing fine motor skills, creativity, and color recognition in toddlers and preschoolers. The water brush included has a white barrel and blue tip, designed for gentle, controlled application. Pages dry quickly and can be reused endlessly—simply let dry or wipe clean. Perfect for travel, quiet time, or classroom activities; promotes screen-free, eco-friendly play without toxic materials. Suitable for ages 2–6, supports early learning through interactive art.
