The fish collecting effect of the high buoyancy type absolute straight line maintenance synthetic is not the ratio of feathers. A "synthetic" for flying is attached to the tail of the worm, and further research is conducted to see if spinning can provide a sufficient flight distance. In addition to the adoption of real color, the hollow structure also features extremely high buoyancy compared to conventional worms. The floating posture was especially particular about this worm. We have carefully selected the material of the eye so that it is horizontal. By floating horizontally due to the lightweight eye, you can approach using the silver screen on the water surface more efficiently. Also, when biting, the body is hollow and bends in the mouth of the bus, so hooking is a good feature.
