The 4.5” Roboworm Straight Tail Worm is what started it all for Roboworm. These worms are poured with robotic precision and feature Roboworm’s exclusive “Salt Release System”. The result of this system is a burst of salt in the fish's mouth when they bite down, this causes fish to hold on longer. Roboworm is known for its expansive color selection that has applications for clear and dirty water. Colors such as Aaron’s Magic, Pumpkin Punisher, M.M. III are colors that are often copied but never duplicated. Roboworms are made in the U.S.A.
