When my daughter put them in her ears she said they burned. I didn't understand what I meant when it occurred to me, she's having an allergic reaction. I don't know what type of metal it is, but it's really cheap. I took it to my jewelers to see if they could at least switch out the post and they said the material is too cheap. If they tried anything that they would probably break. They suggested covering the post in clear polish-2 layers. Still didn't work.

It' a shame. We bought 3 pair and had to return the unused 2 pair. I didn't want her to give them to her friends and their ears turn green.

Furthermore, $45 is too much to spend on a pair of garbage. I'd spend that if it's was at least silver plated. (They were cheaper before the movie came out)
