I have a nickel sensitivity, so was very happy to find your products. I suspected that my daughter might have a similar sensitivity after she had both of her ears pierced in the second position, made the mistake of changing them too soon and misplacing the original stud, and having them become painful and reluctant to heal. I found these earrings online and ordered a pair for each of us. For me they are very comfortable. As soon as they arrived, my daughter switched to them too. Her earring holes began to improve very soon and they healed within days. We are very impressed with your products - safe, comfortable and very beautiful. Thank you so much.
