Ceramic smart ring with integrated sensors. Tracks sleep, activity, and readiness. Syncs with Oura app for insights. Sleek white ceramic finish. Size 8 Petal Please see pictures and video…there is a mark on the ring I haven’t been able to buff out. Since it’s next to where it’s worn on the inside of your finger it’s really not noticeable at all. It’s also not a crack at all it’s just discolored there I am only selling because I have lost a lot of weight and upgraded to the newest one in a new size. Includes original box as pictured and the charger and cord Any questions please feel free to ask. This was purchased in Feb, I’ve uploaded a pic of my receipt as well from Best Buy
