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 that has extraordinary capabilities. When the line is extruded, nylon molecules are “Polarized” 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. JINKAI line has Powerful tensile and Knot strength, with an unequaled resistance to abrasion. JINKAI is manufactured to have a softness and sensitivity which gives you a greater casting distance, with better bait control.
