Need a streamer box? Is the MFC Boat Box too big to fit in your boat bag or backpack? This is the box you want. You could realistically fit 150 or more large streamers in this thing or utilize the 432 slots for stones and large nymphs. Do you need more than 150 streamers for a day of fishing? It’s about the same size as the Bugger Beast Jr(11″ x 8″ x 2 1/2″) but it’s waterproof, twice as bomb proof, and much thinner for storing. It feels like it’s made out of Nalgene bottles. Check out the MFC Fly Case.
