Dri-Mark® U.S. Counterfeit Money Detector Pen, Black

Prevent fraud in your workplace with a counterfeit detector pen, capable of determining if a U.S. bill is genuine or suspect quickly, even in busy environments. The Dri-Mark counterfeit pen marks a small line on a bill and informs the teller if the bill is counterfeit based on the color of the mark against the U.S. bill.
