I’m a 7 and I got a size M/L because I figured if the rings are too big I can at least wear them on my thumbs. My friend has these rings in the smaller size and these ones fit the exact same as the larger size. Not one ring fits any of my fingers. They’re even snug on my pinkies. I asked customer service about this since I’ve tried on the small size and it was the same as the large size I purchased and they said I needed proof. Not sure how I was going to provide proof. I guess if you have a larger ring size than a 6 these are not for you.
