Inside, the clean and stealthy design continues with a matte black base lining. This provides a striking contrast to C&F's signature silver-finished metal foam-changing mechanisms. Built with a focus on adaptability, the internal layout utilizes C&F's interchangeable Universal System concept. It is designed to perfectly accommodate Small-Size System Foams (system foams are sold separately), allowing you to swap out whole selections of flies in seconds. Weather-resistant, highly durable, and weighing a mere 130 grams, this pocket-sized fly box fits effortlessly into any shirt or wading vest pocket. Supplied with exclusive anniversary decals, it is a true statement of functional luxury on the water.
