One each of the microfiber pads that go on the Bottom Burr Carrier and the Bottom Bearing Mount. While they can last for years and years with simple brush-cleaning, sometimes it's nice to start fresh and go back to new parts, just like the day it was finished in our workshop. Precision microfiber pieces are die-cut together with a 3M industrial adhesive backing so they will fit perfectly, the same as we use on our assembly lines.
