How it works?
· Most currency in the world is made out of a very unique fabric that can't be replicated or reproduced; not even by the best counterfeiters.
· Counterfeit detection pens are filled with a unique chemical ink that identifies bogus or fraudulent bills.
· Using the pen to test the currency is quick and easy. Make a mark anywhere on the bill and watch it instantly change color. If the mark stays clear or turns slight yellow you have genuine currency; if it turns black or brown the currency if a fraud; don't accept it. The mark will disappear in 24 to 48 hours leaving the bill unharmed.
