Implant Grade Titanium Internally Threaded Blue Fire Opal Ball Claw Prong

16 GA (1.2mm), Gem: 4mm Material: Implant Grade Titanium 16 GA fits 16 Gauge Threaded Bars. I bought it sometime last year but only bought one ball/end instead of two. Figured I’d get the other one at some point after finding a ring but never did.
