This is a set of two notebooks and pens called "Magic Water Book" that allows you to write with a water-filled pen. I purchased them at 3coins for 300 yen. It's great because you can draw with water, so it doesn't get dirty. It can be used repeatedly as it dries. The notebook has 8 pages, each with a theme in the form of a problem, but you can also draw freely without worrying about the theme. It also seems useful for practicing writing. I will also include one set that has been opened and used for testing. The cover got stiff because I spilled water on it. Please discard it if you are concerned. All items are stored at home. - Product Name: Magic Water Book - Price: ¥300 (tax included) - Size: Approximately 18 x 25 cm - Contents: 2 notebooks and pens - Features: Special material that allows you to write with water - Target age: 6 years old and up Thank you for viewing.
