I bought these because the nose studs I had were too heavy and to put them in you had to go from the inside of your nose out which is hard for me because it is still a fairly new piercing. I like that they insert from the outside in but putting the backs on can be tricky. I have lost the little rubber back every single time I have changed my nose ring. I think I am going to have to buy a pack of just the backs because this seems like a persistent problem.
