These earrings come with post backings. I can also make them as clip-ons, for those without pierced ears or with wraparound hooks for plugs. (here is an example of how they look with hooks- http://imyourpresent.tumblr.com/post/25054132179/new-version-of-my-sweetheart-earrings-for-plugs ). If you would like the clip on or hook version, just let me know in the "Notes to Seller" section when checking out.
