Set of 2 Standard System Foams, C&F Design's most standard fly case.
Designed to hold standard size trout flies from #12 to #18.
Customizing the fly with micro slit foam allows you to easily know your worn out flies and refill them to get ready for your next fish.
It does not crush the hackle wrapped on the underside of the hook shank, so it can store the pattern of your choice.
