The Designer NT Twist Pen Kit Bushing Set consists of three separate bushings, the Cap Bushing, the Center Bushing, and the Tip Bushing. The bushings are threaded onto the 7mm mandrel. The barrel diameter of the bushings serve as a gauge that tells you the size to turn the pen blanks to the correct barrel diameters.
