The stoppers are too small and the holes are too small. They don't fit on a single pair of french wire earrings that I have because the holes are too small. And when I try to put a stopper on an earring that's already in my ear, I can not tell if they are even oriented correctly because (you guessed it) they are just too small and you can't feel which way the ends are pointed. Not worth sending back, but I will be looking for something bigger.
