By far the best desiccant for drying drowned flies and indicators. The finest fumed silica available, and with a brush with just the right stiffness. This powdered dry-fly dressing and floatant is best for delicate dries and those with CDC. Won't mat hackle or hair. Keeps small dries floating longer. Also traps air bubbles on nymphs to simulate an emerging insect. Fly-tying accessory in 1 oz bottle. Made in USA.
