This is a HERZ Wanpaku Rucksack. I purchased this here, but I'm selling it because I haven't had a chance to use it. I've only used it once since I bought it. 【Size】 Width 23 (37 at the bottom) cm Height 34 cm Depth 15 cm Probably size S. The color is chocolate brown. There are scuffs on the corners, scratches, scratches on the metal parts, and three white spots. Please check the photos (they were there from the time of purchase). The key is missing, as the previous owner lost it, so it is not included. Please understand. A smartphone or mini wallet will fit in the zippered pocket. Regarding storage capacity, it is introduced on the herz official website, so you may find it helpful to check it out here: https://www.herz-bag.jp/special/staff/staff56/ Color: Brown Material: Genuine leather
