The longer bar is the 8mm while the shorter bar is the 6mm. I had to order the 8mm because the 6mm was waaaay to short. Currently wearing the jewelry in my nose piercing and it's doing well. Doesn't fit snug (my fault) but it definitely does its job. Love the jewelry, love the packaging, shipping was relatively fast. 10/10 would order again.
Shipping was pretty quick, I got it around the expected time. I don't know my size yet so I ordered the wrong size. But the quality seems good. I'll try ordering again!
