Thrifted this from a local Parisien flea market a few years back and I’m just not using it. I believe the size is in PM. Pls see the measurements at the last photo to make sure. It does not come with the strap nor dust bag. I also don’t see any codes so the possibility of it being authentic is slim. If there’s any chance that you can tell it’s real please do reach out. The trim is made of leather. Overall it still a great bag and very clean interior. Lots of life left with this bag. Will accept best offer.
