The Thinnest Paper in the World

Fascinating.

I once built a cloud-printing app (free printing in exchange for banner ads printed on the pages) and for an initial launch, we installed printers loaded w/ paper across a university campus. A Japanese friend recommended and even sent us paper from Japan (can't remember the brand anymore) to use because he claimed it was some of the thinnest industrial-grade available and this would help us maximize the paper capacity for each printer.
