At Mavrk we're crazy about Euro-nymphing and Tightline angling. We believe that simpler is better when stalking wild river trout so we only offer what you really need. Our mini fly boxes are the perfect "pocket size" for anglers who choose to fish light with minimal gear. Or, choose to carry fly boxes in vest or waders pockets rather than a pack. It measures 5.5" x 3.5" x .6" Also, using multiple small fly boxes instead of single large box can be a better way to organize and access different fly types when you're on the water. It holds 103 flies. Our Mini Fly Box is made with polycarbonate. It's a more material, but it's stonger and more clear that cheaper boxes. Our mini fly box is exactly what most fly anglers need; a compact, easy to use fly box that's water proof and floats.
