Nose ring sizing

Zee • #blackgirlmagic✨ 👸🏽WOOGIRL

Soo I need to buy a new nose ring. I wear L-shaped studs only bc the screw stud ALWAYS migrates in my nose- they never worked. The gauge of the needle I got pierced with is 18gauge(1mm) and the nose ring size was 20gauge(thickness) and 0.8mm in length. But the L-shaped stud ring was short because I couldn’t see the end of the ring in my nostril but it was fully in my nose, just short. What size ring and length should I get? Thanks
