For sale Brand New unisex set of 2 size 9 smart rings. One is rose gold tone and one is black. The black is still factory sealed. I opened the rose tone to try it on then found it’s too big but it’s not used. Each ring comes with its own charging case and cord. The rings track activity, sleep, workouts, heart rate, blood oxygen, blood pressure, heart rate variability and stress via the Da Ring app. Works with iOS and Android. Actual items pictured.
