Review on High-Quality Stainless Steel Ring Sizing Mandrel in Sizes 1-16 by Charlie Conner

Two stars just because it's beautifully made and the numbers are etched into the metal making it easy to read. Everything would be great if the measurements were really accurate. I bought two ring mandrels and two sets of metal ring gauges to ensure accuracy. Both sets of size 6 rings as well as my own ring which is also a size 6 are 5 3/4 on this mandrel. Unfortunately, since its primary purpose is to measure the ring accurately, it doesn't matter how well made it is. I personally would refuse.
