I bought these for my granddaughter because she kept puling her own earrings out. I needed something that would stay in and not come out. When I saw these and read the reviews I had to get them. Well, I was disappointed, I found out that after a few months that my daughter had an infection and that the earrings was the cause. She is allergic to them, they turned her ear green, and they caused her ear hole to close. Now I have to get a ore expensive pair of earrings something that will not turn her ear green
