4 Huron Counterfeit Money Detector Markers 5/15/50/150/375/1500

This listing is for four (4) new markers. The package originally contained five. I had a garage sale and wanted one marker. The pack I bought contained 5 but I have no use for the other 4 that were never removed from the package. The felt markers will make a light yellow, practically invisible mark on regular bills. According to the side of the pen, it will make a dark mark on counterfeit bills.
