This Ultimate Tungsten Putty Duo Pack contains 2 × 10 grams of tungsten, very easily moldable and with very high density. Ideal for balancing pop-ups and fine tuning balanced leaders, the super good grip also makes it ideal for applying to your leaders. The colors can be mixed to create a unique camouflage mix. Tungsten putty is almost 2 times heavier than lead. This means you need half as much to get to the desired weight.
