Smart Money Counterfeit Bill Detector Pen for use with U.S. Currency, Dozen

The Smart Money Counterfeit Bill Detector Pen has been an invaluable asset to my small business. As a boutique owner, I cannot afford to take any chances with counterfeit bills. This pen is easy to use and has proven its effectiveness time and again. I love the peace of mind it brings, knowing that I can quickly verify the authenticity of currency before completing a transaction. A dozen in a pack means I can place them at each register and never worry about running out.
