Platypus Platinum™ is a co-polymer nylon monofilament that gives you a line that has the advantages of low diameter with the value for money that only local manufacturers can provide. 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. Reduced diameter also means more line on your spool allowing you more line (and time) to fight those bruisers from the deep. Platinum™ is thinner than most monofilaments IGFA rated sizes (not 10lb, 25lb or 40lb) Low stretch for added sensitivity and improved lure action. Each spool has 500m line.
