TLDR: HIGHLY recommend these beautiful earrings. As a person with nine piercings, I’ve dabbled in a lot of jewelry. Usually, I purchase all my cartilage piercings directly from a tattoo parlor because I need them to stay put - through workouts, showers, and long walks - and I’m thoroughly impressed that my Maison Miru earrings do just that! I purchase the tiny gold studs, the tiny crystal studs, and the crescent moon threader flat back. The studs are beautiful and despite my fears about the little studs, they have stayed in! While the threader earring was a little tricky because it is small, with some patience and a mirror, I was able to twist on the moon and it has stayed put. I saw reviews the moon fell out and I can see how that could happen if not screwed in properly so I check a few times a week that it’s screwed all the way in and so far so good! Buy these earrings: they’re delicate and gorgeous and excellent quality!
