I purchased this a few months ago. I am listing it for sale because I haven't had a chance to use it. I apologize to the previous seller. Details such as size and material are unknown. It can be used as both an ear cuff and a ring, 2-way. There are signs of use, such as small scratches. The gap in the overlapping part is black, although it's unclear if this was the case originally. It will be shipped in simple packaging. The size is approximately 2cm in both length and width at the maximum. I apologize for the high price due to shipping and handling fees. If you are interested in purchasing, please read my profile before considering. Silver
