I just got my convertiblez earrings. I tried them with a small set of studs. Here's my issue with these: 1) they did not come with those nice small clear plastic ear nuts and with smaller stud earrings regular ear nuts are obviously visible; I will need to go and get a set of these clear ear nuts; 2) the other thing is that with long hair, I would be worried that my hair would get tangled in the ear nut and accidentally pull it off. I've had this happen with stud earrings on my own ears. I would feel safe wearings these only with my hair up and out of the way. Otherwise, I think these are interesting and a nice, cheap alternative to having studs converted.
