The Hanak Metallic tungsten bead directly correlates diameter and weight, and comes in a rainbow of colors. Its multiple reflections are particularly effective on iridescent, pearlescent, or color-shifting rigs where no single hue dominates. Sizes range from 2.00 to 4.00 mm and from 0.06 to 0.43 g; packaging: 20 pieces per bag. First, choose the diameter-weight combination based on the hook and the rig, then select the color.
