【New, Unused】 This is a K18 bracelet. The colors are yellow gold and white gold. (Photo 7) There is a K18 stamp. (Photo 8) The plate-shaped yellow gold sparkles as it reflects light when it moves. The white gold rings also have a textured finish, so they sparkle and reflect light when they move. The design is elegant, but it also has a touch of cuteness with a subtle heart charm ♡ The design is versatile, making it suitable for both formal occasions and everyday wear.＾＾ Another great feature is that because it uses two colors, yellow gold and white gold, it will match any ring you usually wear, whether it's platinum, gold, or silver! We are offering a significant discount for December only! It's perfect as a reward for yourself for working hard this year, or as a Christmas present.＾＾ We plan to ship via Nekoposu (Japanese postal service for small packages), but we can change it to courier service for an additional 300 yen.
