The Big O was Cotton Cordell’s first “million-seller,” the first square-lip crankbait ever created. This proven lure still catches plenty of big bass. The buoyant body and cover-deflecting ability is unmatched by other square lips. Three sizes are available (2-, 2 ½- and 3-inches) in a variety of fish-catching color patterns. The Big O started the square lip crankbait craze, and it’s still leading the charge.
