They are adorable!  Like other reviews, I have to agree that they are a small and I can see how they would be perfect for a child. As an adult, I still love them.  I like how small they are since most of the time I just want something I can wear for days on end that aren't going to turn my ears green.  The only down side is that with my longish nails, I had a bit of a time getting the backs off the the post and then getting them on. That is the only reason I gave it 4/5 stars. But it wasn't such a big deal that I wouldn't repurchase them, like some necklaces that are nearly impossible for me to manage. I will update after I sleep in them to see if they poked me to the point it was uncomfortable.

UPDATE:  Slept in them last night and they are just fine.  And I sleep mostly on my side, and no problems!  So I will probably just leave them in until I want to wear something different, perfect!
