The sides, front, and bottom have a unique design with triangular shapes connected by curved lines. The head shape has a stable fall position, reduces shaking during lifts, reduces tide resistance, and has excellent maneuverability. A bottom touch bumper is used on the bottom part to increase the sensitivity of landing on the bottom and protect the paint when landing on the bottom. In order to protect the leader, high-strength resin parts are incorporated into the line hole, and the hook side is equipped with a swivel socket system, so it can be used not only for floating sea bream tenya but also as a sinker for sea bream mule. Since the bottom position is stable, it is a very effective weapon in shallow areas where there are many bites near the bottom.
