The surgical steel studs you get when you get ears pierced which have slightly different backs and the back snaps into a little groove on the shaft of the earring so they don't move about or come out easily.
Help me understand what these earrings are called - I need to order some for dd2 from Amazon ideally. Shes lost one of the studs and she's allergic to flipping everything else and swimming lessons have made her ear lobe quite sore. I need some more studs asap.
Thank you xxx
