Product Description

  • Unlike many basic counterfeit pens, the BioGuard Pen is enhanced with a patented antimicrobial technology built into the barrel, helping reduce the spread of germs—ideal for shared use in retail and banking environments.

  • The antimicrobial protection is built into the plastic, not just a surface coating, meaning it lasts the life of the pen and won’t wash off or wear away.

  • Like all counterfeit pens, it's most effective at detecting bills printed on regular paper, not currency paper.

  • Yes, it’s completely safe. On genuine U.S. currency, the pen leaves a light or invisible mark that fades over time and does not damage the bill.

  • The BioGuard Pen is designed to detect counterfeit currency quickly by marking paper bills to check for authenticity, helping prevent financial losses due to fake money.

The entire package was opened, unsealed in original packaging in my storm door! You could tell it was intentionally opened not a fluke

It is great that they changed the packaging to blue! When it was black, other employees thought it was a black Sharpie and they'd throw the money pens away. They thought they were dried out! Complete ignorance! With the bright sapphire blue shade, everyone knows these are the money pens.

Good pens for checking fir conterfeit currency. Two pens have markers to check bills. Light color is good, and dark color identifies counterfeit currency. The third one is a combination marker and ultraviolet light. It helps check the strips on currency to detect bad bills. No instructions, which could be helpful. Good value for the price.
