Want the right size but this first!
If you are looking at a Oura ring then this is a must!! It has 12 different size rings that you try on before ordering your ring. It fits on your index finger so it's imperative that you use their guide to determine your correct size. I tried this on my index fingers on both hands to double check my ring size. I don't know what finger I would wear it so I wanted to double check.
