This salt-impregnated Flip-N-Tube is designed especially for flippin‘ and pitching. Strike King's innovative Flip-n-Tubes feature a special patent-pending head which has 1/2'' of solid plastic to hold your hook and a screw-lock sinker in place as well as increase durability. The salt-impregnated Flip-n-Tube's hollow body traps air giving it a more lifelike feel and was designed for flipping in heavy cover. The special 4 1/2" length is perfect for a Mustad Megabite or similar hook. Works great fished weightless as a soft plastic jerkbait too. This is the bait that won Denny Brauer the '98 Classic!
