I purchased this at the vintage clothing store SLOW in Daikanyama. These are eye-catching vintage earrings. You can also wear them like an ear cuff by hooking them onto the cartilage of your ear. I have worn them once. There is no rust or dullness, but there are some fine scratches. (They are only noticeable if you look closely) Please refrain from purchasing if you are concerned. The material is unknown, but it is probably brass or plated. *Some parts of the image are blurred to prevent reflections. Color: Gold
