This is a vintage set of earrings guards. They are still attached to the original card. The card is marked FULLER'S FINDINGS and the guards are 12K gold filled. The guards measure 2-3/4 inches long. I am not certain how these work but they appear to rest over the top of the ear. There is a clip on a chain which must attach to the earring. The guards are in very good condition and have not been used. Please let me know if you have any questions. Thanks for stopping by.
