That is a good suggestion. I will do that since I wasn't sure if a straight flat inner edge like that would be comfortable or not. I do like to wear my bangle as snug as I can get it so it usually requires lots of soap or lotion to get off.
I wear my bangle so tight that when I had an mri a few weeks ago I almost couldn't get my bangle off.

I'd just completed a steroid treatment which made me retain a little bit of water. Lol, good thing I still remember Junkenpo's issue with getting her bangle off buy using the edge of her dresser for leverage. Phew, that did the trick! And then I felt all naked and anxious until I could put my bangle back on after my test.
I don't know how you guys feel, but my left wrist has not been without a bangle on it for the past 8 months that I didn't realize I was going to feel so lost without wearing one.
