Unused. Since it's a set of two, you can wear them on both ears like earrings, making them easy to use for events like entrance ceremonies. Made with natural pearls, the color and shape are beautiful and simple, making them easy to use for both formal and casual occasions. They're also easy to coordinate with your existing earrings. This design is easy to use even if you don't have pierced ears. I received these as a gift, but I have many ear cuffs, so I'm selling them.
