AEROLARRI "Cashin Fiber" is a composite material made from real shredded U.S. money, using 53 patent pending processes and resulting compositions. US cash currency is an extremely advanced fibrous material, much like carbon fiber. Dollar bills still look good after 30 years of circulation, so the secret fibers used to make cash are very robust and proprietary by nature. One idea I implemented is to take shredded currency (the FED does this to retire bills) and use it instead of, and/or to supplement carbon fiber. The U.S. Federal Reserve Bank no longer sells shredded currency to the public for security reasons. They also routinely reject people who ask. And yet, after many meetings at the FED, board approvals, and CIA/FBI clearances, AEROLARRI has secured an exclusive written agreement with the United States Federal Reserve Bank to attain and use shredded currency for this specific purpose. As AEROLARRI is the only company in the world to have a portfolio of large-scale proprietary processing methods and a stable supply of shredded currency, we welcome other manufacturers to contact us for using it with their products. We can make anything, and have a yearly supply of $6 Billion (original value) of shredded currency. AEROLARRI is bound by very tight controls agreed upon in attaining the agreement from the U.S. FED.
