The Strike King Filler Worm is a 6-inch worm that is designed for a drop shot rig, but also excels in other finesse applications, such as on the Strike King Tour Grade Mini Mag Jig Head or on a downsized Carolina Rig Strike King utilizes the advanced Open Pour Technology (OPT) for the Filler Worm. This system allows for more life-like, vibrant colors that mimic natural forage and attract fish. OPT also gives the Filler Worm a layer of salt-infused plastic. This salt, added only along the bottom, allows the Filler Worm to stay upright when it is rigged on a drop shot, creating a more natural presentation for fish that are finicky and more challenging to catch The Filler Worm is offered in 16 vivid, fish-attracting colors that have been developed by the Strike King pro staff Strike King designed the Filler Worm with an extra-wide head to give the worm added strength and durability, so anglers can now use a single worm for longer, with more hours of casting and more fights with aggressive fish
