I was a little afraid to order a hoop. I've had a bioplast stud in my nose since 2011. Recently I lost it while sick n blowing my nose.

This hoop is 12mm because my nose and nostrils are huge. I have come to terms with that and I have accepted it and can admit. Anyway

This hoop was easy to open, insert, and close and IT FITS MY BIG NOSE =]

I love it.no regrets.
I attached picture.
