Vintage Anne Klein cornflower blue leather belt

Vintage cornflower blue Anne Klein leather belt, size not listed but 32 1/2” long, gold buckle. 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.
