I use a plywood nuc box with the lid hooked on the side with a luggage strap hooked to it. I carry all the small stuff (matches, back up lighter, queen catcher, marking pen, queen cage, cork for plugging smoker, etc) in an old candy tin to keep everything dry. My smoker fuel (newpaper and old blue jeans torn in strips) is rolled in a plastic bag to keep it dry. I have two hive tools, bee brush, frame hanger, veil, and a smoker lose in there. Everything fits in the smoker fuel bag if you need to use the box for swarm removal.
It allows me to carry everything I need for a sudden swarm removal in a tight easy to carry multi-use container. If you're making some plywood nucs the cost of one Merrill box will more than cover the material cost of one sheet of plywood that will render you 4 nucs. Whether use a homemade nuc box or a Merrill tool box I'd recommend it. It keeps things compact, forces you to get rid of things you don't actually use, and makes you look very professional.
