River map fly boxes are made in Montana from handpicked boards and individually handcrafted with great care regarding quality and detail. At Stonefly Studio we work on bringing out the natural color and woodgrain in each of our fly boxes. The boxes undergo hand sanding, and we use clear lacquer. We never stain our wood so each box retains its own individuality and beauty. The river maps are hand drawn then customized on the computer to fit on our fly boxes. Once the fly boxes are crafted and the design work is done, the boxes are individually placed and engraved in the laser engraver which receives its instructions from the computer like a printer.
