My elementary school-aged daughter used this. There are adjustment marks on the strap. There are some yellowed spots on the seams of the zipper. The zipper itself is cold-colored, so I don't think it's very noticeable. There is dirt on the opening of the front pocket and on the seams. It hasn't been used much and has been stored, so there is no loss of shape. It will be packed and shipped in a flattened state (photo 8). It is also possible to ship it without flattening it for an additional 300 yen, so please comment before purchasing. If you have any other questions, please ask. I am also listing this on other sites, so please comment to confirm availability before purchasing ( . .)"
