Oura Ring 4 – Stealth Black – Size 12

Oura Ring 4 – Stealth Black – Size 12 Selling my Oura Ring 4 because the size ended up being too large for me. I originally wear size 11 and thought size 12 would fit better on a different finger, but it still feels too loose. The ring is fully functional and works perfectly. Battery life is still around 4–5 days depending on usage. Stealth black / matte finish. There are visible signs of normal use and some small scratches from daily wear, but nothing affecting functionality. Comes with the original charger and all original accessories/packaging. Great choice if you want to track sleep, recovery, HRV and activity without wearing a smartwatch.
