Our custom logo printed ultra slim fly box. Made from tough, clarified polypropylene, these 1/2" thick minimalist boxes will provide great storage for nymphs while keeping the bulk down. This box is fitted with a flat sheet foam insert that has tear drop openings/slits to accept flies. The fly or hook bend is inserted backwards or 'backed' into the tear drop slit which holds the fly secured but eliminates the need to push the hook point and barb into the foam which will destroy most foam boxes in no time. This one isn't like that, with the fly 'backing' into the slit these boxes will last a very long time. A super slim box for the needs of every angler, and one that is Jeff's favorite for housing medium nymphs .....nymphs that are size 18 and larger. Dimensions 7" long x 4" wide x 1/2" thick. Our most popular small stream and DH stream fly boxes.....Great for holding 'DH Junk."
