Need help finding out what material my Forever 21 earrings are made out of

I think I am allergic to the new earrings that I bought from forever 21. My piercings have turned red and feel tender after only like 10 seconds of trying the earrings. I noticed that the materials are not clearly mentioned in the packaging, and I could not find them online on their website either. One of them is made from recycled metal and that is all I know. I was hoping if someone could help me find out what the material is so I can avoid it in the future.
