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 and midge patterns and options while keeping the bulk down. This box has a foam liner mounted inside with tear drop slits to hold flies. Flies 'back' into the tear drop and the foam lasts longer because you aren't 'hooking' the fly into the foam but instead 'backing' the bend of the hook backwards into the foam tear drop slit. A super slim box for the needs of every angler, and one that is Jeff's favorite for housing medium nymphs (bead heads in particular). This box is great for flies larger than size 18 , both bead head and non bead head. Dimensions 5" x 3.5" x 1/2".
