I bought this lip stud as an alternative to my metal ring and hoped that I could wear it for work so as not to be as obvious. When the stud arrived I was eager to put it in, so I sanitized it and prepared to wear it, however the internal threading did not serve to keep the gem in place but popped in and out easily. Not good for something worn on the lip which moves quite a lot. I decided to try it anyway and much to my dismay it was very uncomfortable, the ring seemed to catch on my teeth more than other studs I've worn and with the gem easily popping off, it was not a good scenario. I do not recommend this piece of body jewelry to be worn on the bottom lip.
