Counterfeit Detector Pens are easy to use and require no training. Anyone can simply use the pen to put a small mark on the bill to check for authenticity. The specially formulated iodine ink reacts to wood-based copy paper leaving a dark brown or black mark indicating a probable counterfeit bill. If the bill is authentic and the paper is fiber-based, the pen will leave an amber mark. These antimicrobial protected pens also help prevent bacteria and fungus from developing on the surface of the pen. Each pen features a black barrel and measures 5.5 Inches long.
