The internally threaded tops in this collection are made out of Argentium sterling silver and 14-karat gold (the threaded screw on the back is steel for durability). Each one comes with a compatible 316L surgical steel backing, but you can also choose to use them with your own 18G and 16G jewelry as long as the thread pattern matches (0.9mm).
Internally threaded labrets make awesome cartilage earrings because the flat backing is super comfortable to wear against the side of the head! They work perfectly for tragus piercings, helix piercings, and conch piercings. You can also use them in your lobes or nose piercing as long as you can wear either 18 gauge or 16 gauge jewelry.
