* The hottest new style is like a temporary tattoo for the ear - get the gauged look for a day without permanently stretching your ears! The front and back of these earrings is split in half, a post is attached to the front of the earring, and a tiny hole is made in the back section and filled with rubber to grip the post as it slides in. Light and fun to wear! * Size: .75" in diameter. * Materials: Carved white cow bone with surgical steel posts.
