There are two kinds of fly boxes. One that you carry a bunch of flies in - pack or boat box, and two, one you carry with you when you're fishing, either in your jacket, pocket, or waders. This is the later - a small, light, thin box I carry with me when I swing flies for Steelhead. I use this box in the summer or for my smaller flies. Holds five flies (can be more) up to three inches in length (max 3 inches).
Comes in two variations:
1. As is - no tubes
2. With tubes to protect fly fibers and flash from being crimped when closing.
Actual Size: 150 X 85 X 25 millimeters (6 x 3.3 x 1 inches)
