Anyone else do this with their boxes? I know the boxes we had in the Air-wing had the red foam.
A lot of places do it any more. In factories it is part of what they call 5S (five-s) It has to do with cleaning , organizing, blah, blah, blah. But putting the tools in foam is now the "big" thing to do. So large in fact that there are now companies out there, that if you give them a list of the tools that you have, the drawer sizes, they will CNC cut foam to your tools or you can submit drawings for them to make it to.
