Used U.S. Military surplus-issue Wheeled Medical Chest
When Military medical personnel need to get vital supplies moved in one piece, these Cases get rolled out! Who knows what sort of field 'action' they may have seen during their service.
One thing's for sure: no matter what sort of paces they might have been put through, each was built to withstand them all. The rugged construction and top-shelf materials were designed to weather even the harshest conditions and still come out fighting on the other side.
