The dot tail is a worm that was created to obtain more fishing results in such situations. The hollow spherical tail, which is the biggest feature, seems to move briskly, but it is moderately braked by the ultra-thin fins at the rear to produce a delicate and soft natural action. Furthermore, in the bottom stay after landing, the buoyancy of the air lifts the tail, and the ball and fins receive water and act fluffy and automatically. Effectively appeals and eats bottom range baits against targets that are unbalanced. In addition, by designing the body part to be thicker, it is easier to detect changes in the tidal current from the feeling of resistance, and it is possible to approach the position where the fish will be localized more accurately.
