Cliff Day's Worth Fly Box

From AvidMax.com

Originally designed as a pocket box for guides on western tailwaters, we have found lots of other people like it, too. The high energy magnetic pad securely holds small flies (open it with confidence in the wind), and larger patterns are held by the self-healing foam strips. Stuff it full of flies that you know will work, grab a few basics, a fly rod, and head to your favorite water.
