issei has modeled a big bait inspired by G.C. Hassflat Hass, as well as the hass (ketabasu) that inhabit Lake Biwa and other rivers. The bait is designed to have a lively action, wiggling its body aggressively just below the surface of the water, creating a splash. It can be used with a slow retrieval or in a dead-slow retrieve for rivers and drifting, as well as for roaming bass in Lake Biwa. The unique feature of this bait is that when a small twitch is applied with the rod tip, it shakes its head sharply. It comes with a middle lip that allows it to dive to a depth of 1.5-2m, and can be replaced with a separate hard tail or lip designed for the Hassflat 180. The tail section is designed to hide the movable parts, and it is equipped with lip hooks and split rings. The price of the G.C. Hassflat 180F is ¥4,980 (excluding tax), and it is available in various colors such as Murakami Shad, Ayu, Hass (Lotus), Red Haraburakku (Red Haulback), Yami Hass (Dark Lotus), Murakami Red, Natural Chart Back, Hiuo (Milking Fish), and Night Shad Gold.
