The Fish Head V-Lock Swimbait Head was designed by Elite Series Pro, Greg Vinson, to meet the demands of a full time touring pro. The patent-pending �V-Lock� keeper locks the swimbait onto the head allowing for multiple catches without changing out the swimbait. The round head design includes 3D holographic eyes and multi stage paint patterns making it very realistic to bass. The Fish Head V-Lock Swimbait Head can be paired with both hollow belly and solid body swimbaits. The V-Lock keeper and recessed cavity allows the swimbait to fit snugly against the head without the use of glue! The Fish Head V-Lock Swimbait Head is available in six sizes (1/8, 3/16, 1/4, �, �, and 1 oz ). Sizes 1/8 oz. - 1/2 oz are 3 per pack and the 3/4 and 1 oz are 2 per pack.
