Raqs Rings Invisible Practice Rings for Zills - CLEAR

I think the measurements listed on the size chart are the actual inner and outer diameter of the rings rather than the size of zills they're meant to fit. Large was much too big for my 2.25 inch diameter zills.

These are SO GREAT. My partner is a bartender and is asleep when I normally practice. When I have these on my zills, he can't hear a thing through his door. Total win for me. They were a little hard to get on at first, but it gets easier when you know what it feels like to get them on. Otherwise - The S/M for item fits the student size, and if you are getting the larger **performance** zills, then you'll need the M/L size. The first reviewer is correct.
