This is a thick, genuine leather business bag. The surface leather and lining leather combined are about 4mm thick, and the overwhelming texture of the leather is attractive. The size is approximately 29cm tall x 39cm wide x 7cm deep (measured by hand). It has been stored at home and has hardly been used. I like craftsmanship and have modified it by hand so it can be carried as a backpack. If you feel a connection, how about it? The drawbacks are that I have lost the key, so the flap can be closed but not locked (there is no inconvenience in use), and there is some slight soiling on the back (photo 10). Please consider this before purchasing. #BusinessBag #Backpack #Other
