These Green-as-Green knobs are not consistently reproducible, so this set of 3 will remain a one of a kind set. They would make a lovely shock of color on any 6 mm or 6.3 mm shaft. A brass insert and set screw allow for a perfect fit on round or spline shafts.
Sold as a set of 3 knobs. Each knob is 1.5 inches long, .75 inches wide, .75 inches tall at the back shoulder. Made from art resin with brass insert and set screw.
