Wapsi Tungsten Slot Beads are an excellent option to help your fly sink deeper in swift currents. These beads are made from tungsten, which is up to twice as heavy as brass and heavier than lead or countersunk beads. The slot design makes it easier to tie your fly by slipping the tungsten bead past tight hook bends. The fit is exceptional on jig hooks. You can find Wapsi Tungsten Slot Beads in gold, nickel, and black nickel colors right here. Heavier than lead for a faster sink and deeper presentation of nymphs, streamers, and other flies in fast-moving water Slot for easy sliding around tight hook bends or angles on jig hooks Quantity per pack: 10 Bead size (in.)
