The Counterfeit Detector Pen is one of the most simple and convenient means available for identifying forged currency. Mark bills with the pen to reveal any trickery: if the marking retains its amber color, then the bill is good to go. However, if the marking turns to black or brown, you’ve got a good idea that something’s afoot. This pen also uses antimicrobial protection so the pen itself remains pristine in spite of frequent use. If you’re accepting large bills, counterfeit provisions are a must and none make it easier than this Counterfeit Detector Pen.
