Used by Yuzuru Hanyu Black, Size 40 I bought this a while ago because I liked it, but I don't usually wear necklaces, so I never had a chance to use it and it's been in storage. It's unisex, but the size is 40, so I think it's more suitable for women. Also, it's now Metax, and this Aqua-Titanium product is a rare item that is no longer manufactured. Thank you.
