We fly fishermen carry flies in all types of contraptions. Some work very well and others leave a lot to be desired. There are so many choices out there it can be mind-boggling. BQA carries a terrific selection of fly boxes from clear and see-through, to floating foam, boxes with built in micro-slits to full on waterproof designs that will keep your flies dry if you happen to fall in. The fly boxes we stock, we use.
