The unique "hard protect resin processing" realizes an ultra-hard finish that is not easily scratched while maintaining suppleness. Furthermore, since it does not become cloudy for a long time, it is also effective for feeding. By adopting non-stress spooling, quality is maintained at a high level without giving extreme stress to the line. Uses a thin connecting spool (No. 0.6 to No. 5) It fits easily in your pocket, can be connected, and the size (pattern) can be changed quickly. Comes with a spool band that is convenient for stopping the pulled out thread.
