I use that exact same Flambeau box pictured and love. I can fit all my ice
jigs on one half and in the other half I have it filled with about a doze spoons. Once you lay a spoon in there you have to adjust how the hooks lay, but it keep buying spoons and still haven't got to a point where I can't close (so I guess I need more spoons).
Also its a really tight seal so worries about water/snow/slush getting in and its a really hard outer shell that looks like it could really take a beating.
I highly recommend that box.
