These magnum-sized thin boxes were an instant hit at our store. The 522-Slit version is perfect for trout nymphs, small to medium dry flies and chironomids.
These boxes are a highly efficient way to carry tons of flies. Each box is 12-inches by 8.75-inches but just under 1-inch wide. They are great for anglers fishing out of a boat when you can keep these boxes nicely filed into a tackle bag or for keeping your "master supply" of flies organized at home.
Molded from nearly indestructible ultra-clear plastic.
Dimensions - 12 x 8 3/4 x 1 inches
