Black faux leather shoulder flap bag

I have a faux leather flap shoulder bag purchased from the store Foreign Exchange. The chain is in decent condition showing some oxidation throughout (see pictures) but all the faux leather is intact and not unraveling. On the outside, zipper pocket on the back; inside, 2 slip pockets on one side & a zippered pocket on the opposite side; lining is clean; no tears no rips; used twice. Very classy piece for your wardrobe. The turn knob on the front also is showing signs of oxidation (see pic)
