I am in the process of listing several hundred micrometers so please check my other items. These are all from the inspection office of a very large manufacturing company that closed last year. These were all in service. We will guarantee them to calibrate or return them within 30 days. Most of these will have some sort of engraving on them. Please check out the up close photos.
