Flambeau's Blue Ribbon Twin Fly Boxes were designed to offer twice the fly storage space using the patent pending Vertical Friction Foam (VFF) technology consisting of rows of vertically slit foam that securely holds flies between the pads using friction without allowing the hook to pierce the foam. Each precision fit fly box features a 360 degree rubber gasket on each side. Holds up to 252 flies.
Size 6.25 x 3.75 x 1.875 Blue Ribbon Waterproof Twins off twice the space with VFF storage on both sides. Double-sided translucent lids, holds 252 flies.
