The workhorse of the Tacky Line, the Original RiverMag Fly Box features automatic storage when time is of the essence. Ten compartments provide specialized organization for each type, size, or color of fly, while silicone walls prevent mixing between distinct patterns. A strong, magnetic base and clear lid mean you’ll spend less time fumbling with your fly box and more time on the water. As with the rest of our line of fly boxes, the Original RiverMag is constructed using 100% recycled plastic.
