Titanium Earring Ball Back (1 Piece)

So I ordered 10 of these because I have a lot of earrings... loved the look.... 3 of them just fell off and one white gold diamond is lost they're not very secure and tight and it's really disappointing since they were exactly what I was looking for and was ready to purchase more ..... make the silicone inside tighter it will fix the problem

These are ok. I like the look but if you have nails it can be difficult to get them on as they are small.
