The Hanak Classic Fluo brass bead puts less strain on the rig than a tungsten bead of comparable diameter, in red. The red color complements black, brown, or copper-colored nymphs well, adding a warm accent. Brass provides a more moderate sink 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.
