5,Mōkī Me te Pahū
Ko nga taura kua kikii ki te kaata, ka whiria ki runga i te pahū rakau Bakelite & Fumigated.I te wa e kawe ana, me whakamahi nga taputapu tika kia kore ai e pakaru te kete me te ngawari ki te hapai.Me tiaki nga taura mai i te makuku;kia matara atu i te wera nui me nga korakora ahi;ka tiakina mai i te piko me te pakaru;ka tiakina mai i te ahotea miihini me te kino.
Te roa o te tarapi:2000-5000m/reel.
