Oura Ring 4 in Silver Size 8

Size 8. Purchased on 9/18/25. It's too big so need a smaller size otherwise would not be selling. Comes with charger. No box. Typical scratches/signs of wear after one year of wear.  Oura Ring 4 brings you closer to what matters most — your health. The updated all-titanium design is powered by Smart Sensing, a new sensing platform that doesn’t just measure your biometrics, it adapts to you, providing insights into over 50 health metrics including sleep, readiness, activity, heart health, stress, metabolic health, and women’s health. Oura Ring quietly and comfortably monitors your health and with 5 to 8 days of battery life — you can forget it’s even on.  App and subscription required.
