Dri Mark's 15-pack counterfeit bill detector pens are pocket-size marker testers made in the USA that instantly flag suspect U.S. currency with a dark line on counterfeit paper.

Keep cash-based sales protected without slowing transactions: these compact pens are a simple, reliable tool to screen U.S. bills at point of sale. The CFD15PK contains fifteen Dri Mark counterfeit detection pens, each formulated to react to the starches in counterfeit paper. Built by the original U.S. manufacturer, these pens combine portability with longer-lasting ink so small businesses can check notes quickly and confidently.

How quickly can I check a bill during a busy shift?

You can screen a bill in seconds — simply draw a short line across a white area of the bill and watch the mark. A light or yellowish mark indicates authentic currency; a dark brown or black line signals likely counterfeit paper.

• One-second mark and read process keeps lines moving.
• Compact, pocketable size fits staff aprons or cash drawers.
• Designed for repeated use throughout a shift without slowing service.

What makes these pens more durable than standard markers?

Each Dri Mark pen contains three times the ink of older models, offering many more checks per pen. Precision-fit parts and a non-roll cap design reduce drying and maintain long shelf life when recapped properly.

• Approximately 10,000 marks per pen under typical use.
• Secure cap prevents drying when stored between shifts.
• Rugged construction intended for retail and hospitality environments.

How reliable are these pens for U.S. currency?

These pens are formulated to react to the cellulose and starch composition used in many counterfeit papers, providing a fast visual cue that flags suspicious notes. Dri Mark is the original U.S. manufacturer and patent holder for this style of detector pen, with decades of point-of-sale use backing their effectiveness as a first-line screening tool.

• Specifically designed to test U.S. currency substrates.
• Used widely by restaurants, retail, banks and entertainment venues.
• Intended as an initial check — follow up with other verification methods if uncertain.

How should staff store and use the pens to maximize lifespan?

To preserve ink life, recap the pen firmly after each use and store horizontally or upright with the cap on. Avoid prolonged exposure to heat and ensure the cap is fully seated to prevent evaporation and drying.

• Recap securely after every use to avoid dry-out.
• Room temperature storage away from direct sunlight is best.
• Replace pens when marks become faint or inconsistent.

Who this product is for: The Dri Mark CFD15PK is suited for any business that handles cash and needs a fast, low-cost way to reduce losses from counterfeit bills. It's ideal for small shops, cafes, bars, food trucks, event staff, and front-line retail employees who want a portable, easy-to-use screening tool. While highly practical for everyday checks, these pens are a first-step detector — pair them with other verification practices and staff training for the most reliable fraud protection.
