The Days Worth Fly Box was originally designed as an incredibly stout "day box" for trout guides. The first time you open a Days Worth Fly Box you will see and feel the difference. It has a strong magnetic bottom to securely hold small flies (open it with confidence in the wind) and self-healing strips to handle anything up to a size 2-weighted woolly bugger. Very durable clear plastic with brass pin hinge. The Days Worth Fly Box is one of the finest small fly boxes available.
