Thank you for viewing. I am selling these items because I don't use them. I've only worn each item once or twice. Both necklaces are collaborations with marie and are made of stainless steel. The gold-colored metal parts have some discoloration. Those parts might not be stainless steel. They have freshwater pearls. The bracelet is a collaboration with pen, and the earrings are a collaboration with yumi, I believe. Please refrain from purchasing if you are sensitive to used items, as these are pre-owned and inspected by a non-professional. I will put them in small ziplock bags and ship them via Nekopos (a Japanese delivery service).
