I believe these are all made of plastic. I think they're from when plastic products were popular. They were in a box in the storage room at my parents' house. It might be fun to repurpose them into earrings or something. They'd also be cute for a woman to wear on the sleeves of a dress shirt or blouse as a playful touch. They've been stored at home for a long time, so there may be some age-related deterioration. These are used items, so there may be minor oversights. Please understand this before purchasing. Returns are not accepted.
