I purchased a set and they are beautifully made and high quality. However, I noticed one of mine wasn’t so tight. It would pop loose now and again from very light pressure and I lost it within a few weeks of having them. I suggest taking these out before sleeping, showering, etc. They aren’t heavy or big of course, so it may be hard to notice if one goes missing until it’s too late.
Update: I’m extremely lucky; it was found at work and returned to me. It was bent more when I got it back, but I was able to fix it and made sure to bend it to a point the pressure was tight once clasped.
