This is a Porter shoulder bag. I purchased it from a local recycle shop and used it once or twice. I don't know much about it, so I don't know the model name. The size is relatively small, making it easy to use everyday. (It's about the size to fit A4-sized items) There are some minor scuffs and scratches, but I think it's still usable. This is a used item, so please refrain from purchasing if you are sensitive to such things or have any concerns.
