Thank you for viewing. My daughter used this for about two years, starting around the 3rd grade of elementary school. It's a box-type bag, so it's easy for children to put things in, and she liked using it. Size: Approximately 29cm in height, 22.5cm in width, and 12.2cm in depth. The inside is clean, and the outside is also in good condition, with only a few scratches and marks, possibly from a pencil. There are marks where the name was written on the bottom edge of the outside of the bag, which have been erased with a marker. Please check the photos. This is a used item, so please understand. When shipping, it will be folded and simply packaged. Thank you.
