The Scientific Anglers Compact 164 Angled Waterproof Fly Box is a unique little fly box that allows you to have larger and smaller flies together on the same side of the insert.  The unique angle of the insert gives more space between the lid and the foam that holds the fly on one end for larger flies like hoppers but then gives up space on the other end for smaller, low-profile flies like beadheads or parachute flies.

 

Design:
• Holds small poppers in a thin profile, holds streamers as well
• Unique slanted center panel gives you the room for medium/small poppers
• Waterproof, single hand closing with see though lid
