Revolutionary vibration with a lightweight board body. That is "KEEBURN". Its greatest feature is its overwhelmingly excellent speed of movement, which sets it apart from conventional metal vibrations. This good action that can be realized only by the board body induces reaction bite from bass in tough condition. And lift & fall, which is often used even in the midwinter. Along with the lightness of the lift, the movement that can induce bite at the time of the fall is important. The KEEBURN has the stability of falling straight down, with a swaying “shimmy fall action” that triggers trigger bite. Benefits from good balance and reduces thread entanglement on hooks. An excellent vibration for usability hardbait.
