Internally Threaded Titanium Belly Button Ring — ASTM F136 (14G, 1.6 × 8mm, 5/8mm Balls)

A timeless everyday essential, this belly button ring is crafted from 100% Ti-6AL4V-ELI ASTM F136 implant-grade titanium — the gold standard for sensitive skin and healing piercings. The internally threaded design means no exposed threads pass through your piercing during insertion, making it gentler and more comfortable than externally threaded alternatives. Measuring 1.6mm (14 gauge) with an 8mm curved barbell length and 5mm/8mm ball ends, it's sized to the industry-standard navel piercing fit. Finished in a clean natural titanium color, it's hypoallergenic, nickel-safe, lightweight, and built for daily wear. A must-have basic for every belly ring collection.
