I purchased this at a nightfruiti store in Korea two years ago. I haven't worn it since I bought it, but two years have passed, so there's a bit of blackening when you look closely. It's not noticeable when wearing it, but if you're concerned, you can use a metal polishing sheet sold at 100-yen shops, etc. Instant purchase available.
