Montblanc crossbody leather bag

Montblanc crossbody leather bag. I bought this at auction for $390 and it was sold as authentic Montblanc. I have no way of knowing if truly authentic other than the markings in several places and hardware. It seems to be made extremely well and genuine leather. There are small scuff marks as pictured, but nothing big. The interior is a bit “crinkly” sounding so not sure if that’s how these bags are made. Just a crinkly material I think. It is a beautiful bag and well taken care of, just too small for my needs. Please look at all photos as they are very accurate to bag condition. Thanks for looking!
