The Magnetic Graduate and Vertex Supreme Pen Kit Bushing Set consists of three separate bushings, the Cap Bushing, the Center Bushing, and the Lower Cap Bushing. The bushings are threaded onto the 7mm mandrel and use small stepped extensions that insert into the brass pen tubes and center the tubes on the mandrel. The larger diameter barrels of the bushings serve as gauges that tell you the size to turn the pen blanks to the correct barrel diameters.
