You know that solo earring you’ve kept for years, hoping you’ll find its lost mate? And now your favorite pair sits unworn, because you’re afraid one might fall off? Liberate them from the jewelry box when you replace their backs with these locking clasps. Precision-crafted using repurposed smartphone technology, they fit any size stem, and can’t detach unless you lift and pull a small knob. Jump from the high dive wearing diamonds. Dance all night in the ones from your hubs. And keep hope alive for those lonely solos, ‘cause you never know. Choose gold or platinum, with or without optional clear backings for lobe support. Made in Japan of surgical stainless steel.
