Precision Die Cast Ring Finger Gauge 1-15 USA Standard

These ring sizers are made of lightweight die cast aluminum and are marked with USA sizes 1 thru 15 with half sizes for a total of 29 individual ring sizers. The opposite side is marked with diameters in mm from 12.45 mm thru 28.83 mm. This is a very nice and precise set of ring finger gauges.

We checked these gauges using a high quality digital gauge and found the marked diameter in millimeters to be "spot on". That is impressive accuracy to a hundred of a millimeter!
