Got the same issue on big lures/jigs. Gonna cut PVC to size, cap one end and put a small crossed bungee across the "open" end. Then just carry it in a bag.
I have a whole bunch of nylon gimme bags that I get at education conferences. They're great for holding smaller tackle boxes or folders.
On my own boat a 2 gallons bucket with cut PVCs to have the jigs stand up. On a charter trip I just carry just enough jigs to last for the trip in a Plano box laying the jigs flat. They sell really neat jig bag made by Shimano and other manufactures.
