Hareline's mottled tactical tungsten beads are a fresh take on a standard fly tying bead. These beads feature a matte finish with contrasting mottled speckles to add color and contrast to your nymph and other fly patterns. And since they're tungsten, they'll drop your fly down like a rock to get down to where the fish are biting. These beads have proven to give many fly fisherman an edge when the fish are being picky.
