Exactly what I wanted and now I have lots of spares. Exactly as described.

I've always found it hard to use earring backs that not only hold a larger earring but click in so you can go out in confidence that your earring won't fall out! Ive worn earrings before where I have lost an earring because the backs are too loose, but now I can wear my earrings with confidence that I won't lose them. These backs are amazing and they literally 'click' with all earrings so they aren't going anywhere!

Keeps my earrings from falling out. Almost invisible .
