This is a blanc iris ring. I purchased it from the official website, but AP STUDIO also carried it. It's actually a set of 3, but this is a set of 2. Single finger Double finger Please refer to the official website for the sizes. I've also measured them and included the measurements, but please allow for some error. I've used it quite a bit, so there are some scratches, but I think you can still wear it and enjoy it!
