These bubble filled orange knobs are not consistently reproducible, so this set of 2 will remain a one of a kind set. Designed as a bold accent color for the Yellow Spiral Drive, 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 2 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.
