This unique set of brass picot gauges is a Grizzly Mountain Arts original design! The entire set telescopes inside each other and then slides neatly into the Holy Land olive wood gauge case. The four size increments are: 1/4, 3/16, 1/8 and 1/16. Also included is a 2 inch brass ruler. A certificate of authenticity for the Holy Land olive wood will be included with this picot gauge set.
