Review on 14k White Gold Plated Earring Backs, Sterling Silver Locking Earring Backs for Studs - Fits 0.032-0.04 inch Earring Posts with Card Slots (4pcs/2Pairs) by Barbara Simmons

What can I say, these are locking earring backs to replace yours. The only thing I would like to point out is that they are difficult to hold and put on and take off if you have big fingers. stay mine The only other thing is that they "snap" into the groove toward the strut end as intended. If your ears are not very big, the earring can hang forward. Mine are holding up a bit and I'm thinking about getting a plastic washer to hold them. It might make these locks difficult to grab to remove, I'm not sure. Overall I like them and they don't irritate my ears.
