Want to give yourself a little advantage next time you're throwing worms find this on fishingcompleteinc.com ? The Zipper Shakin Worm combines the popular ribbed Zipper design with a thinner bodied worm made for shaking. The ribs cause bass to hold onto the bait longer, giving you a better chance to set the hook. While the thin, flat tail imparts the shaky action that drives fish wild. Designed for Texas rigged presentations and shaking in front of hungry bass.
