I'm selling these because I don't use them. I don't usually wear earrings because of my job, and I've lost them twice, buying them again each time, so I haven't used them much. Please understand that these are used items stored at home. Thank you. Hallmark present. I can include new silicone backings if you'd like. ★I have the sales certificate, but there's a memo written on the bottom right of the cover. I will include it if that's okay with you.
