This item is (100) Clear Soft Rubber Earring Backs a.k.a Earstoppers. These are Bell-shaped and not ridged like our other clear Earring backs and are slightly softer rubber. These are put on the ends of ear wires to prevent the earring from falling out. These have saved me from losing some of my favorite earrings in the past and I swear by them.
