"Ar. Head Jack Upper" is based on the "horse mackerel". In addition to improving hooking performance, it is designed to make it easier for horse mackerel to be sucked into the upper jaw. By adopting fine wire, sharp sticking and good suction are realized. Excellent penetrability and secures overall strength during hooking. Center-balanced round head provides excellent stability. A rich lineup that assumes a delicate approach with a jig head rig and a combination with a variety of separation rigs. [Color] NS Black
