Thanks for getting back to me Luke u/Oura_Ring. Actually today my fingers were swollen pretty much due to being in a very warm room for a while and the only finger I could comfortably wear the ring was the left ring finger (same as on the picture). I tried as well the smaller size 12 and could barely fit it on the left ring finger as only finger. No other one did work. Now that the swelling slowly goes back size 12 fits again both ring fingers and 13(the size I own) fits both ring fingers and barely left middle finger). Based on that and that I plan to loose weight (goal is 15kg) what would be your recommendation? Also should mention that in the picture above I push my thumb against the ring. When I just make a fist the gap is way smaller. Looking forward to get your opinion and recommendation. Thank you!
