  • 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

These pens are great for anyone who sells to the public! Unfortunately, we were given a fake $50 bill at our garage sale last year. It will not happen again with these pens!
