Thank you for viewing. I purchased this at ZOZO, but I ended up not wearing it, so I am selling it. As you can see, it is unopened. Length: 12mm ~Quoted from ZOZOTOWN~ SBG Surgical Stainless Steel Kihei Chain Necklace. Simple and goes well with any style. Made with stainless steel, which is less likely to cause metal allergies, so those with metal allergies can use it with peace of mind. The stainless steel material, which is compatible with metal allergies, is resistant to rust and scratches, making it ideal for everyday use. This chain necklace is overwhelmingly popular in various fashion genres, such as clean fashion, street fashion, and Korean fashion. It's a stylish design that can be worn by both men and women, even as a pair, making it a recommended accessory for gifts, such as birthday presents for boyfriends or girlfriends.
