  • Simple, Reliable, and Effective
Size: 2 Pack
I purchased this counterfeit money marker to keep on hand for peace of mind, and it works exactly as described. The marker is easy to use—just a quick swipe on the bill and you immediately know if it’s genuine or suspicious. It dries quickly and doesn’t smear or damage the currency. It’s lightweight, affordable, and convenient to keep at a register or in a drawer at home. I tested it on several different bills, and the results were clear every time. Having this tool makes me feel much more confident when handling cash. For anyone who deals with money—whether in a business, at events, or even just casually—this is a simple and inexpensive way to protect yourself. Highly recommend! ... show more

The Perco Counterfeit Money Detector Pen is a simple yet essential tool for anyone who handles cash regularly. With the increasing circulation of counterfeit bills, having one of these pens on hand gives you peace of mind when dealing with large denominations. Whether you’re running a business or organizing an event, this pen ensures that the bills you receive are genuine. I ordered these pens for an event, and they arrived on time in perfect condition. Although I ended up not needing them because someone else had already brought some, I was still impressed with the product and the overall purchase experience. The pens work exactly as advertised, giving you a quick and easy way to verify the authenticity of your bills. The price is also very reasonable, making it a great value for the security it provides. If you want to feel secure about the cash you're handling, especially when it comes to larger bills, I highly recommend the Perco Counterfeit Money Detector Pen. It’s reliable, easy to use, and gives you confidence that you’re not getting stuck with counterfeit money. ... show more
