i bought these for my second and third holes that way i can keep them in without being stabbed in the head 🥴 anyways, best purchase! they are twist off and on, which was just a little bit tricky, but i did it!! they haven’t come out since i out then in. i try to keep them tightened any chance i get! you get 8 different sizes which is awesome!! #amazon #find #steal #deal #earrings #flatback #flat #comfortable #ear #hole #jewelry #diamond #rhinestone #earring #stud #flatstud #favorite #staple
