This is a bag that can be attached to the waist belt of a baby carrier! It can also be used as a shoulder bag♪ When I was using a baby carrier, it was convenient because I didn't have to take my bag off every time. It's an Ergobaby product, but I used it with baby carriers that weren't Ergobaby too. There is some fading on the front as shown in the fourth photo, but other than that, it's very clean and you can still use it for a long time♪ Thank you!
