USA Made Universal Kiteboarding Kite Pigtails set of four -- one red, one yellow, two grey Save your kite lines and your kite bridle set. Set of four universal pigtails. Sewn in loops on both ends. Color coded two grey, one blue, and one red. You can put knots in both ends -- they come set up with a knot in one end. Much less expensive then buying new lines. By using pigtails you reduce wear on the most stressed spot on your lines.
