I used this bag for about 2-3 weeks when I was a student. The shoulder strap broke quickly, and it's been sitting in the closet ever since. The inside is mostly clean, but there are some areas on the bottom corners that are a bit white. The shoulder strap wasn't sold at Ayanokoji, so I attached a new one made of fabric that won't break. It's adjustable, so you can adjust the length for a handbag or shoulder bag. You can also remove it and replace it with your favorite strap. Please see the last photo for the size. It seems this type is no longer sold.
