This solid 14k yellow gold flat ball nose stud has a tiny ball on its back end that holds the nose stud firmly in place. We call it a flat ball, but it is really like a flat circle that sits comfortably flat against the nose. This type of nose stud, with the ball on the end to hold it in place, is often called a nose bone or nose pin. The nose stud features a 2mm flat ball. High quality at a great price. This listing is for one single nose stud. 1-14NOS-NE7014
