Today's story is that they've got a really slick way of protecting a CD. Just put it on a piece of paper and fold the sides as shown, making a pentagon shape. I've been doing it like that ever since. Unlike normal sleeves and cases, it'll shed dust from most angles. I don't know if it's the product of an intensive research program or informal ingenuity, but it's a damn fine trick.
Fully biodegradable to boot!
The one in this picture was folded by an actual Chinese Military Intelligence Interrogator!!
