球形耳扣

These little backings are a lifesaver, my pair from a different set got lost at a wedding and these popped right on with a satisfying click. The fit is snug enough that I don't worry about them slipping off during the day. Only wish they came in a two-pack for the price, but they work great.

I was worried these wouldn't fit my standard earrings, but the ball backs screw on smoothly and stay put all day. Perfect simple solution for a missing backing.

Lost the back to my favorite pair of sterling silver studs and these spheres fit perfectly — the threading is smooth and they hold tight without slipping off.
