For those of you less fortunate than I (having been one of Uncle's Lost Children for a couple of decades), let me explain the wonders of MRE toilet paper:

Inside a brown paper sleeve about 15x30mm marked "Lighthouse S.F. CA." (means packed by the blind) reside approximately 24 individual sheets, 100x100mm, of the thinnest mechanically possible toilet paper ever devised by the Devil.

From personal experience, using said packet gives you exactly two swipes about equivalent to 220 grit sandpaper. But, on the plus side, it WAS free (issued).
