Nako Tungsten Worm Weights

200% More Sensitive than Lead - Made of 97% pure tungsten, which is denser than lead for a compact profile and much better signal feedback from underwater objects. Laser-Etched Size - Weight is clearly printed on each piece. Easy to identify the right weight in your tackle box while fishing. Eco-Friendly - Tungsten is non-toxic and safe for the water, fish, and human body, offering a superior alternative to toxic lead weights. Insert-Free & Line Safe - Diamond polished inner bore ensures no line damage, eliminating the need for plastic inserts. No Chip or Fade - Features a special solvent treatment and durable coating that is far more robust than standard painted weights.
