The original square-bill crankbait, the Cotton Cordell Big O remains as deadly today as when it started the whole bass-crankin, cover-knockin, reaction-bite revolution. More than a million Big O crankbaits sold in the first year showed that the world had found a whole new way to load up on largemouths and smallmouths alike. With its buoyant body, short lip and high deflection, the Big O remains the top square-bill on the market today. Sizes:1/4 oz., 1/3 oz., 3/8 oz. Colors: (559)Oxbow, (560)Baby Bass, (561)Olive Craw,(562)Bluegill. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Hard Baits.
