A collection of packout rollers, packing containers, and add-ons have been on the market in my area Northern Tools. I do think its in jewelry stores. YMMV. It was in fact a hundred bucks involving this “Milwaukee Packout Rolling Toolbox — 21.1in.L xx 19.9in.New location xx 20.6in.H, Modelcertainly not 48-22-8426”.
