The industry's largest custom-poured worm manufacturer has taken its classic straight worm design and added an exclusive salt release system. Bass devour salty Worms and won't let go of them. Which is why Roboworm has developed the ultimate salt impregnation system. Most Worms hold the salt on the outside which dissolves fast. Roboworm actually embeds the salt in the head of its worm, so it dissolves at a slower rate. The salt release system weighs the worm bait down and lasts up to 30 minutes before completely dissolving. As the salt dissolves, the worm floats to the water's surface. Ideal for drop shot presentations.
