These custom anodized shift knobs are truly one-of-a-kind. Each shift knob is polished to a mirror finish before anodizing. During the anodizing process, all color combinations are done by hand using an intensive technique. The anodizing process builds a strong layer making the shift knobs extremely durable and scratch resistant.
