Both were purchased a month ago, but they didn't fit, so they have never been used and have been stored on a shelf, making them almost new. The gold ring was purchased online and the silver ring was purchased at a jewelry store, for a total of about 3500 yen. I don't remember the exact size of the gold stainless steel ring, but I think it's a size 11 (11-13). This is a set of two. Scratches/discoloration... None.
