Thank you for viewing. This is a nylon backpack purchased several years ago at an Agnes b. store. It's a packable type, so it becomes small and can be carried around. The backpack straps are striped, and the inside of the backpack is silver. I think it's a rare type because it's quite old. It's been stored for a long time, but it hasn't been used much, so it's clean without any stains. The zipper hardware also has no peeling, and there is no deterioration or stickiness inside. The silver fabric looks wrinkled and appears dirty, but it is not. A4 size fits. Width: Approximately 31cm Height: Approximately 37cm Depth: Approximately 10cm I'm sorry, but please refrain from price negotiations. We do not accept returns under any circumstances, so please do not purchase if you have any concerns.
