This is a Saint Laurent Cabas bag. I purchased it at a store in Kobe City. To prevent swapping, returns and exchanges are not accepted. If you have any doubts about its authenticity, please use a trusted authentication service. Please only purchase if you understand that returns and exchanges are not possible. I've used it about 10 times. It comes with a shoulder strap, so it can be used as a handbag or a shoulder bag. I'm selling it because I haven't been using it as much since my child was born.
