These are really great for cartilage! I have a really sensitive ear, and every other ring has made my ear hurt. Also, every other ring I have used has been so hard to close or clasp. This ring is super easy to clasp, I did it alone with no mirror. I have also forgotten I even have it in. It’s not painful, or irritating. I really love these rings, and I will purchase them again. I bought black 8mm ones, and they are perfect size for my cartilage. I would definitely recommend these to family and fSee full review
