We've all been there, you want to change patterns, so you grab your fly, clip it off, and like that... your fly line and leader float downstream. The Tippetac solves that problem. Before clipping off the fly, simply jam the tippet material into the rubberized wedge/slit in the Tippetac and it is held firmly while you find a new fly. This nifty little tool uses two super strong, rare earth neodymium magnets to make sure that it stays where you want it. The magnets also function to temporarily hold flies. You will find it's a great place to quickly store a fly or two as you change out your rig.
