The flat head goby has a flat shape like a trilobite, but when you actually pick it up, it is surprisingly thick, and its cross section follows the traditional hexagon body of the Goby series. The deep reverse ribs engraved on the body firmly grasp the water and at the same time generate complex and strong waves, making the bass notice not only shallow but also super deep over 15 m, inviting serious eating peculiar to ring worms. The body weighs just under 14g (4 inches), and even with a no sinker rig, a long cast that is convincing is realized. The deep inverted rib structure makes it easy to bend the thick body, so it can be easily folded in the mouth and exhibits excellent hooking performance. It retains a high degree of versatility that has been trained in actual battle tests, such as a slit that can firmly hide the hook point and a thick body that does not warp even when skipping.
