From the makers of the world's best and oldest fishing line, Platypus Platinum is the result of many years of research and development. Platypus has created a thin diameter monofilament without compromising qualities like abrasion resistance or knot strength. Thinner diameter means decreased friction on the line so that your lure can work deeper and is more responsive due to the low-elongation (stretch) properties of the monofilament. It also means more line on your spool, thus allowing you more line (and time) to fight those bruisers from the deep. Fish with the best!
