Thank you for viewing. This is a popular silver earring by Yurika Akutsu. I loved and used these when I bought them, but I haven't worn them in the last few years, so I've stored them in a box from another brand in a dark place. When listing them, I wiped off fingerprints and sebum with消毒用エタノール (disinfecting ethanol), so I think there is little dirt. I have not confirmed any discoloration. One of the earring backs is missing, so I've been using a different type. Please check the photos. It's not visible when worn, so I think it's not a problem, but please refrain from purchasing if you are concerned.
