K10 heart motif earrings, 4°C. I received these as a gift but have never worn them and have kept them in storage. The outer box has a little bit of dirt on it, so I've listed them as "Like New." The photos don't show it well, but the earring backs and the earring posts are stamped with K10 4°C. There is no warranty card! Thank you! ♡ I will discount them by 300 yen if you don't want the box. - Design: Heart motif - Material: Metal - Color: Pink Gold Thank you for looking. Instant purchase OK.
