Since I have a lot of people asking about sizing? I now have a plastic ring sizer available for sale on my Etsy site. This adjustable ring sizer is easy to use and convenient to store for future use. Measures in US whole and half sizes 1-17. My rings are available in quarter sizes too, just in case you are in between. Also, remember to add a half to 3/4 size onto your size for the wider spinner rings I offer.
