This Midge Waterproof Fly Box is a small, double-sided fly box with a waterproof seal when closed. The crystal clear lids allow you to see your flies with the box closed. There are 5 rows on each side of the box, each row with numerous foam slits to store lots of flies in a small space. The clear lids are securely closed with a pinned latch and a rubber gasket forms a watertight seal.
