Plano's foam lined fly boxes are the perfect solution for organizing your tiniest trout flies. The high density foam compartments securely cradle hooks and bodies so flies stay put, while the simple one handed opening and closing keeps you fishing. The foam material has a smooth finish that won't snag delicate fly parts. Available in multiple sizes to suit the breadth of your fly box collection, from Panfish patterns to dries and nymphs for mountain streams.
