Aventik Super Large Capacity Fly Boxes Slim Foam Clear Lid PP Collection Fishing Boxes Competition Fishing Hook Tackle Boxes(2X24LD)

I got these NOT as field boxes but to use them to organize, sort and store my bulk flies. Their large size and simple construction makes them shares for field use but at this price, and with the different foam options and potentially massive storage capacity, I can buy as many as needed to keep my you tying flies organized en toto. Currently I have two for dries and emergers, and two for nymphs, buggers, and terrestrials for close to 1000 flies.These boxes are pretty shallow so they are fine with most of my trout flies. However, large hoppers and saltwater streamers may not fit cleanly and get compressed or crushed by the lids. So I use different boxes that are deeper for those largest flies.
