Each 1 lb. spool contains approximately 504 linear feet with a 340 lb. breaking strength.
This twine is specially black treated and dried before it's put on the spool.
It has many advantages over twine treated by "spool dunking."
It is uniformly and deeply coated from one end to the other - no "zebra stripes" or tar globs to come off on your hands.
It's dry, easy-to-tie, and holds knots well.
