Alpha Ring Sizer

A plastic ring sizer, the zip-tie kind, not a paper strip. Measure at the end of the day. It should pass the knuckle with a little resistance, then sit snug.

These metals don’t resize. Get the size right, then order the ring. Wrong size anyway? Free exchange for 90 days.

Ships on its own so you can measure before you buy. See the size guide for how to use it.
