Details Our summer box! The Big Cliff(TM) is the perfect dry/dropper box. It was designed to fit in the shirt pocket of most fishing shirts and still hold lots of summer patterns. Load all your small dropper flies on the magnet and the larger bugs (dries, nymphs, streamers) in the foam. It has the capacity to hold all the bugs you need for a day of dry fly fishing. Fits easily in a fishing shirt at 5 3/4" X 3 ⅝" X 1 A 1/4" size.
