This is a backpack for going to and from nursery/kindergarten. Approximate size: 23cm tall, 22cm wide, 12cm deep. The wide depth allows for plenty of storage. Prioritizing functionality, it's durable, stain-resistant, and lightweight, making it very easy to use. Features a large YKK zipper that's easy for small children's hands to open. The fabric is thick and durable yet lightweight, and the material is easy to wipe clean. The back has cushioning that doesn't easily lose its shape. It has non-slip material on the underside of the shoulder straps to prevent them from slipping off even when running. Includes a name tag pocket. The large outer pocket is convenient for items like communication notebooks. The inner lining of the backpack is made of a thick material that doesn't bend, and it's sewn in place so it won't shift or get lost. Purchased from a bag shop, it's a sturdy item that cost around 3000 yen. It's durable, so there's not much difference in its condition. The yellow lines on the edges haven't had any tubes come out or torn. When I bought it, I thought it might be plain, but it was great in terms of functionality and ease of use, so I'm glad I bought it. Adding patches for customization is also a good idea.
