Purchased from an authorized retailer. Can be used as a duffel bag or backpack. Used a few times, but I haven't had many opportunities to use it, so it has been stored in a dark place. I have tried to include any areas of concern in the photos, so please take a look. * The tip of the zipper has cracked due to aging. * The part used to cinch the opening when used as a duffel bag is broken and missing. * The inside is slightly sticky. ● Other: Please be sure to check my profile before purchasing. It will be folded up small for shipping. Please refrain from purchasing if you are nervous about home storage or are looking for a perfect product. Thank you. ★ For those who understand Japanese, please.
