The Hanak Classic Fluo brass bead puts less strain on the rig than a tungsten bead of comparable diameter, in the chartreuse color. Choose chartreuse for a high-contrast rig, especially with a black or dark olive body. Brass provides a more moderate descent rate, while the fluorescent finish creates a distinct splash of color. Sizes range from 2.00 to 4.70 mm and from 0.03 to 0.31 g; packaging: 20 pieces per bag.
