Quoting Eℓizabeth |12weeks|:" i hate those too, i could never change it."
I'm fairly certain it's my own fault for getting it pierced through the scar tissue from my old one.
I got it pierced, the next year I had to put in an invisible one, and when I was sleeping it got caught and fell out (didn't hurt or anything), and closed up before I woke up.
I wanted it again, so a few months later I got it done in the same spot, and the screw they put in was so freakin' huge I had to change it after a few weeks. I've had the same one in since-- will not come out. It twists and moves no problem, but the tiny ball at the bottom is too big for the hole.
