The JAG Solution Pens eliminate the biggest enemy to a sharp hook - rust. Running the pen over a newly sharpened hook point eliminates/slows down corrosion by applying a thin coat over the bare metal. The pens are odourless, dry in 60 seconds and manufactured using only ingredients that are 100% safe to aquatic life. The natural colours can also be used to camouflage hook links, tubing, swivels etc. Pack of two pens, the Weedy Green and Silt Brown colours.
