Daiwa J-Fluoro is a new fluorocarbon leader material from Daiwa. Like the braided line from Daiwa's world-renowned J-Braid series, J-Fluoro is Japanese-made fluorocarbon manufactured using the most precise line extruding technologies in the world, making the consistency of J-Fluoro leader next to none. The crystal clear line is virtually invisible underwater and Daiwa's new spool band technology makes the leader material easy to dispense as the elastic band controls the tag end on the leader spool. This also allows more line to be fit on a smaller spool so precious tackle box or boat storage space isn't wasted on bulky spools.
