Oura Ring 4 – Stealth (Matte Black) – Size 12 - $95 (North Capitol Hill)
QR Code Link to This Post
Up for sale is my Oura Ring 4 in Stealth (premium matte black finish), size 12. This is one of Oura's more expensive finishes, offering a sleek, understated look that doesn't scream I'm tracking every biological function of my existence.
The ring was used for approximately 5–6 months and works perfectly. It does have some cosmetic scratches from normal wear, which I've reflected in the price. Nothing that affects its performance.
