This is our 3 Pack Counterfeit Money Detector Pen Banknote Tester Currency Cash 2in1, which offers a reliable and convenient solution for verifying the authenticity of banknotes and currency. 

Features: 

• These counterfeit money detector pens feature a dual-action design that allows you to perform two tests in one. The pens include both a UV light and a counterfeit detection pen, providing multiple verification methods to ensure the authenticity of banknotes.
• The counterfeit detection pen contains a specially formulated ink that reacts with the starch in paper-based counterfeit bills. When applied to genuine currency, the ink appears clear or light yellow. However, when applied to counterfeit bills made from wood-based or chemically treated paper, the ink will produce a dark brown or black mark, indicating the bill may be fake.
• The built-in UV light allows you to perform an additional verification test by illuminating the security features present on genuine banknotes. UV lights can reveal fluorescent markings, watermarks, security threads, and other features that are invisible to the naked eye and difficult to replicate on counterfeit bills.
• Using the counterfeit money detector pens is simple and straightforward. To perform the counterfeit detection pen test, draw a line on the surface of the banknote with the pen. If the ink remains clear or light yellow, the bill is likely genuine. If the ink turns dark brown or black, it may be counterfeit. To use the UV light, simply activate the light and shine it over the banknote to reveal any hidden security features.
