The ultra-realistic bait with aluminum foil inserted into the body like a spine is the pintail worm Flash J. Flash J Shad is a form of enthusiastic request for "a shad tail version of that Flash J". The big feature is the swimming action unique to Shadtail. By making the space between the body and the tail thinner and designing the tail itself to be smaller, you can produce a bait-like swim. In addition, even a no sinker attracts the bus with outstanding stability. Excellent compatibility with wheel heads and screw hooks.
