Thank you for viewing. My child used this for about a year, but it was only used when going to塾 (cram school), so I think it's in very good condition. It's very light, has an inner pocket, and the back is mesh. The zipper has a Yankees mark on the pull, making it easy to open and close, and very user-friendly♪ There is one spot where the fabric above the mark has become slightly fuzzy, so please check the image. Hand-washed and home-cleaned. It will be compressed and folded for shipping. Anonymous shipping.
