Maybe they needed something for insulation in the walls and ceilings in Colombia. Crumpled paper serves as a good insulator.

I gave a wad of these bills to my daughter to play with, there is not one left, it has ended up in the trash. A few years ago on the Colombian border, Colombians bought them, but I don't know the reasons.

Someone found a great use for the useless banknotes, handicrafted objects like purses. Very useful!
I keep a 1,000,000,000,000 dollar Zimbabwe bank note on my wall to remind me of what happens to real banknote fiat! I also have a $1,000,000 US (fake) note on that wall to be an even stronger reminder.
