The Hanak Round+ tungsten bead directly correlates diameter and weight, and comes in a matte black finish. Matte black is the most understated choice for a dark nymph or a rig where the bead needs to blend into the background. The calibrated round shape provides a versatile base for tying weighted nymphs. Sizes range from 2.00 to 6.40 mm and from 0.06 to 2.00 g; packaging: 20, 10, 7, and 5 pieces per bag, depending on the diameter. First, choose the weight needed for the desired depth and current speed, then make sure the diameter fits the hook you’ve selected.
