A model that uses hand-made needles traditionally used in the Boso area of ??Chiba prefecture."BinBin Tenya Boso" is a model that uses tungsten material for the head and opens up a new world for Tenya fishing, and uses hand-made needles traditionally used in the Boso area of ??Chiba Prefecture. By giving the needle a nemuri and making the needle tip inward and making it an acute angle, both "good hooking" and "difficulty in breaking" have been achieved.
