The gap between the fat body with outstanding appeal and the slight vibration created by the thin curly tail is attractive. Even in a severe situation where strong waves do not eat, only the tail is made to act as "Piro Piro" and brought to the part-time job without a sense of caution. By deliberately making the shape of the curl long and loose, it acts lightly with "Piro Piro" in a form that extends from the slow, and makes it look as if a small fish is alert and swimming. Until now, the worms used in severe situations have been pintail worms, but this makes it possible to attack in new ways.
