This is the exact perfect look that I was searching for, for my helix piercing. I absolutely love it! I had a similar one in and removed it, because it looked too big and "clunky." This one, however, is sooooo dainty and pretty! I'm so happy with it.
Only thing to note is that these are threaded in a different way than some other flat backs. When I ordered it, I got a 5mm (because I didn't know better, and just looked up "what mm for a helix.") Unfortunately, my helix piercing was a newer piercing, so the 5mm was too short, at it's current stage of healing. Grrrr, I was so eager to wear it! But none of the posts my piercer had matched this one, so they couldn't just sell me a longer post. But luckily, I was able to buy a new, longer post from AdornMonde which arrived pretty quickly, so that I was able to wear the prettiest new piercing!
