This sterling silver lever-back ear wire features a 50mm-dia. beading hoop dangle. Add decorative beads, charms or other components (min. hole size is .032") to the hoop, then insert the wire end into the tube and crimp the tube to securely and permanently close the hoop. A hinged closure helps protect against loss and makes this earring a snap to put on. A short length of open channel is perfectly sized to accommodate the short, arched wire that goes through the ear. Simply insert the wire and close the lever over it to secure the earring in place.
