Steel grey Anne Klein vintage snakeskin belt

Steel grey vintage Anne Klein snakeskin belt, matching snakeskin buckle with gold accents, size medium, 32 1/2” in length. My mother used to be the seamstress at a fancy dress shop in the early 1980s. She purchased these belts at this dress shop and is cleaning out her closet and allowed me to list them on Poshmark. I have conditioned all leather & reptile skin belts with Angelus leather cleaner and conditioner but cannot ensure that the skin is not brittle because they 30+ years old.
