The dynamic patented process by which JINKAI is produced and precise blending of just the right nylons are the secrets that have unleashed a line with extraordinary capabilities. As the line is extruded- nylon molecules arepolarized to maintain a soft center with a tight outer surface. This allows JINKAI to remain sensitive and responsive- yet provides incomparable toughness and strength in micro-fine diameters. The result is an unbeatable combination of the most ideal qualities.
