Tru-Tungsten® Force Beads are made of a natural composite material. This special "force" material attracts fish and produces an extremely loud and unique sound. Each bead is coated with a Duraseal™ coating for added durability and to match our colored weights and your plastic lure to make a uniform bait. They are lead-free and environmentally friendly. The added sensitivity will allow you to Discover the Feel® and the increased loudness will allow you to Fish Harder!
