Sony's Clie PDAs back in early–mid-2000s came with a CD in a paper tray-package. It was a thin box of sturdy paper, the size of a ‘jewel’ case, but from a side of it slid out a tray, also of paper, with the disc on it. And it didn't come out all the way but was held by something inside. I realized then that Japan treats its papercraft seriously.
