This case is something I came up with while yard saleing with my mother. I wanted something to protect my markers rather than carrying 5-8 separate cases as I was doing. When I saw this suitcase with dividers, the light bulb came on. Works like dream, and I already had the foam and the case was only 5.00... I made a smaller version that held a marker, fiber wrapped tank, hopper, and a few other accessories.
