JAG The Solution Camo Pens are designed to remove the main drawback of hook sharpening: rust. A thin coat applied around a freshly sharpened hook point helps eliminate or slow down corrosion. The four natural colours can also be used to camouflage hook links, tubing, swivels, and similar tackle. The coating dries odourless within 60 seconds and is manufactured using ingredients that are 100% safe to aquatic life. The pens are sold in packs of two different colours. - Black and Gravel Brown - Weedy Green and Silt Brown
