Why Oumo is different

Made for real piercings

Piercer-founded, woman-owned. Implant-grade titanium piercing jewelry made for sensitive skin, real prices, every body.

01 — Material

ASTM F136 Titanium. Not surgical steel.

Implant-grade. Zero nickel. Won't react during healing. Safe from day one.

02 — Back

Flat-back. Not butterfly.

Smooth disc against your skin. No bacteria pockets. No red marks at night.

03 — Engineering

Internal & threadless. Not external.

Smooth posts that don't drag your piercing channel during insertion.

04 — Stones

5A CZ. The highest commercial grade.

Not the cloudy 2A on Amazon.
