When I was younger, I could wear any type of earrings I wanted. It did not matter the material they were constructed of. I went a period of just not wearing anything. When I decided to wear earrings again, I couldn’t. My ears had become so sensitive. I have tried other Hypoallergic with no success. These were different. At first, I thought they were going to start the itching process. I was wrong. They have been perfectly fine. I received 6 pair of the “diamond” look. They are very small and dainty. The size is perfect since I have multiple holes in each ear. The backs definitely stay on.
