I have to disagree with you on the choice of Izal. It was similar to 'tracing paper' in appearance and didn't stand out as much once on the pitch or draped over the goal as your bog-standard (pun intended) white toilet paper.
Also, those Izal toilet rolls were always too small they'd often fully unravel before clearing the terrace.
Anyway, back to their intended purpose - it failed miserably (although I conditioned myself never to have a 'number two' in school).
