Made from heavy tungsten, designed to easily slide onto your hook link or main line and ensure everything is pinned down to the lake bed, keeping your hook length out of the carp's way. Not only will these help with sinking your mainline they can also be used for fixing the top bead when fishing the naked chod. Simply side the sinker on to your line and a wide bore tapered bead will softly grip it, forming the perfect but safe stop. Natural no spook colour. Pack of 10.
