This is a set of jewelry ring gauges sizes 3-13 (14.0mm-22.2mm). A pair of calipers is recommended to ream and check each one to fine tune. I got mine within .010in which is accurate enough for manufacturing tolerances. I personally used para-cord to keep them all together. The specs were taken from a jeweler website and are as follows:
03 - 14.00mm
04 - 14.80mm
05 - 15.60mm
06 - 16.45mm
07 - 17.30mm
08 - 18.20mm
09 - 19.00mm
10 - 19.80mm
11 - 20.60mm
12 - 21.40mm
13 - 22.20mm
