So here's the issue - I loved these and bought two. This was my first time using threaded earrings so there was a huge learning curve to use these in my lobes. The back goes through the back of your ear and then the front threads into the back by twisting into it. There was a lot of trial and error but I figured it out.
Cut to a week later after I wore them 24/7 all week, one of the mustve come unscrewed and fell out. I realized it when the back was still in my ear (since that's the part that goes through the hole), but lost the front which makes the earring pretty useless.
I was really bummed so I bought another one... and -- long story short -- after another frustrating session of trying to thread the front to the back (because the "post" is really small!), I lost it down the drain. :( I've bought three of these and have one. I'm going to wait to see if they come out with a push pin version and if that happens, I will buy another. Otherwise, I give up!
