I found the source! The US postal service "flat rate" boxes, (free). They have very fine corrugated board, and the top layer peels off with no residue/ripping, mess! Quality stuff, half the size (thickness, goooves etc.) as normal boxes, but strong.
Try them. (the USPO flat rates, for some reason, takes apart cleaner than Fed Ex boxes.)
I discovered this this month. It put my 15mm Boxer Rebellion pile of buildings and frames, back in "ready to make much progress" status, as I now have easy and the preferred style roofing material.
