Wow~~ This is a whole new world. I was a bit hesitant because it said it was one-size-fits-all... The product is pretty, but I bought it just to try it out since I didn't want to worry about the size, and it’s really amazing and great. It’s comfortable, too. You just pull it slightly to adjust the size, so you can simply clip it wherever you like. I can just roll up the remaining chain and tuck it in, so it doesn't get in the way at all. It’s really convenient and great. And being pretty is a given~!!!

It is an amazing ring where you don't have to worry about the size. I really want to wear it on all ten fingers, and I can. It is really great.

It was so pretty, but I lost it less than a week after receiving it. The tightening part was loose, so it slipped off my finger before I knew it and disappeared. I'm so disappointed and upset.
