1.5" [38 mm] Billiard Ball Shift Knob (#3 Ball)
1.5" [38 mm] Billiard Ball Shift Knob (#3 Ball). Made from a real billiard ball (colors are molded in, not painted) that's bike sized. Not so heavy that it shifts itself when you hit a bump and not so big that it bumps into things, just the perfect size. 3/8"-16 brass threaded insert and supplied with a stainless jam nut, so you can get it right side up.
