I own a couple of these for different rivers I like to fish. They are secure, both holding flies and staying closed, easy to open and have good capacity. I really like this streamer box for when I’m going to be wading and only carrying a sling or chest pack. Where this box really shines is when you need to limit what your carrying. I can fit this box, another box for nymphs and dries, a leader wallet, and various other accessories inside my chest pack. Another thing I really like about this box over some others is the height on the inside, so when you close the door your not smashing down your feathers, fiber, etc. you could also toss a couple nymphs or terrestrial patterns in this box just to have them on hand, the foam holds them fine.Also, if your in the market for a new fly box to carry a bit of everything, the fulling mill tactical max is awesome. It has huge capacity, it can hold nymphs, dries, smaller streamers etc,. It also has all the other great qualities of this streamer box.
