An all-round soft bait that pioneered a high-appeal action worm whose body rolls in synchronization with the action generated by the vibration generated by the large shad tail. This W action brings the fish together and brings them to eat, and the texture peculiar to the soft lure does not give a sense of discomfort, so the bite is also outstanding. Not to mention the threaded sea bass, all fish eaters from flatfish such as flatfish to hairtail are targeted. In particular, it is used nationwide as a standard item that must be aimed at flatfish from surfing.
