Black/Gray striped CONVERTIBLE Purse

Bought this beautiful bag at the swap meet so I don’t know brand. Bag is “convertible” because it can be transformed from over shoulder purse, to backpack, to cross body. Inside lines with black and white striped fabric as well as a zipper pocket and two open pockets. Bag zips and clasps. Only used a few times still in amazing condition, no rips/stains zipper fully functional. Size is 9 1/2” tall by 11-12” wide (at base) and inside expands to 4-5”.
