Purchased at Jewelry Nemoto several years ago. I'm selling these because I don't have a chance to wear them, as I use other earrings. I'd like to pass them on to someone who likes them. I've forgotten the name of the material, but I believe it's an allergy-friendly material. Disinfected with alcohol.
