The Magnetic Vertex Pen Kit Bushing Set consists of two separate identical bushings, the Cap Bushing, and the Tip 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 barrel of the bushings serve as a gauge that tells you the size to turn the pen blanks to the correct barrel diameters.
