★ A bead unit that allows you to easily and reliably change your tie without worrying about shaking or wind on board! In addition to a change stopper that allows you to easily change the tie or worm even on board a ship where shaking or wind is a concern, beads with a diameter of 5 mm that have the effect of spreading the tie to the left and right so that the tie does not interfere easily are installed. The owner's "Cultiva Jigger Light Red Sea Bream" is used for the hook. We have a lineup of 3 sizes that can be used according to the situation, from M size that corresponds to all seasons, S size that is most suitable for low activity small bream in midwinter, and L size that corresponds to high activity large bream in summer.
