I bought these to use either for my daughter (1.5 years old) or myself. I know they are sold as children's earrings, but I have four holes in each ear and needed some placeholders. I was wavering on giving my daughter hoops, because I didn't know if she may pull them out. So I got one pair of hoops and one pair of studs. After about 5-10 minutes of discomfort for my daughter...with her wriggling and crying, I realized I was never going to get them closed. As you can see from the photo, you have to push in the hook into the other end. This is usually easy for me because I have other earrings like this, but this was impossible to close on my daughter's ear. So, after a few minutes of torture, I put the studs on her instead and put the hoops on me...again, it took a very long time for me to get them closed. I think these could work if I was putting them on an older child or adult, but putting on toddlers or self is nearly impossible. I'm wearing them now and they are pretty, so I will most likely never take them out!
