The Roboworm Curly Tail Worm features a thin subtly curled tail, that delivers an irresistible finesse action. The Curly Tail is made with Roboworm’s signature robotic hand poured triple color technology, as well as their exclusive ‘Salt Release System’. Whereas most worms have salt either just coating the plastic or trapped inside, Roboworm infuses the head of the worm with salt allowing it to leech out slowly during your cast. A burst of salt is released when a fish bites, so the fish holds on longer, resulting in a better catch ratio.
