My daughter got these for her nose ring. She's allergic to some metals. She liked them so much, I ended up trying them, and finally, comfortable earrings for the first time ever! I don't even feel them there, which is amazing. The latch is smooth, seamless, and secure.I never knew that I had what must be a metal allergy. I would try to wear my other earrings and they were always uncomfortable, and I'd take them out after a few hours. I haven't taken these out since I got them.See full review
