Vintage white shell like earrings

Vintage white shell like earrings. I’m not sure the card matches the earrings. In good pre-owned condition. The back of one of the earrings looks like it has a spot that has rubbed off, but I can’t feel it when I rub my fingers over it-see picture for details. From a smoke free and pet free home. See something you like? Make me an offer. I can’t wait to do business with you!
