This is a Columbia bag I bought about 6 years ago ^_^! It can be used by both men and women! * The length of the shoulder strap can also be adjusted☆ * Approximately 20cm tall, 30cm wide, and 10cm thick * There are some scratches on the zipper (photos 6 and 7), but other than that, I think there are no particular problems☆ It has pockets, so it's convenient for organizing your belongings (^o^)! After giving birth, I started using a backpack more often, so I decided to sell it, hoping someone who will cherish it will buy it☆ Thank you for looking ^_^☆
