Selling my smart ring: Oura Ring 4, Stealth finish (matte black), Size 10. ⚠️ PLEASE NOTE - GENUINELY BRAND NEW & SEALED: Unlike many fake or misleading listings you might unfortunately find on Vinted, this item is TRULY "New with tags" (Brand New in Box - BNIB). As you can clearly see from the photos, the ring is still inside its original shipping box with the factory pull-tab seals completely intact ("Health is a beautiful thing"). It has never been worn, tried on, or even taken out of the box. This ring was sent to me directly from official Oura Support (I can provide proof of the replacement/shipping email to serious buyers)
