Purchased last year at a jewelry store. These were originally earrings, but I fell in love with the cute design and had them remade into Piercing Charms. They are K18, but I can't find any hallmarks. When I had them remade into charms, perhaps the part that had the hallmark was replaced. Therefore, I would like to sell these to someone who trusts them. Thank you. I plan to ship them via Yu-Packet Mini without the box.
