This backpack is made with traditional denim fabric from Ibara, Okayama, coated with polyurethane. It's likely discontinued now. The shoulder straps show some deterioration, but it shouldn't affect use. It's a very convenient bag that can hold A4 files and a B5 laptop. To ensure the quickest delivery time, we may change the shipping method from Rakuraku Mercari Bin to Yuyu Mercari Bin, or vice versa, depending on the time of purchase. Thank you for your understanding. If you have a preference for either Yamato Transport or Japan Post, please let us know before purchasing, and we will do our best to accommodate your request.
