These weren't what I was expecting, but I like them anyways. After going through tons of different brands of nickel free and other types of earrings for sensitive ears and having bad reactions (and wasting a lot of money) I was hesitant to buy these, but I love them! They don't bother me ears at all. They're actually plastic posts and backs which are much more comfortable that you'd expect and easy to put in. They're a little cheap as far as quality, but also in price, so it's not a problem! They are smaller than I expected and from the picture i was expecting there would be a variety of sizes in teh box, but they are all the same size. Would definitely reccomend!
