WOO! Tungsten Neko Rig Nail Weights are made with the highest quality premium tungsten that you've come to expect from us. We designed them with ribbing along the body to ensure that when you put them inside a soft plastic bait, that's where they stay. They are ideal for Neko rigs and adding a little extra weight to make your swimbaits sink faster. Much more compact than lead counterparts of the same weight, WOO! Tungsten Nail Weights provide an eco-friendly option for rigging soft plastics.
