If black is your thing, you must have this Onyx Curve Labret. It's not a question. If you don't have a cartilage, conch, or lobe piercing to put this bad boy in, I urge you to get one!
It is sold by piece and is implant grade titanium made at 16 gauge (1.2mm) and 5/16" (8mm) long with internal threading. It is perfect for initial piercings, nickel free, and ready to ship!
The Semi-Precious Stone Labret in Black Agate goes beautifully with this!
If you need a different length, titanium labret bases are available here.
