Dri Mark 351B1 Counterfeit Bill Detector Marker Pen, Made in The USA, 3 Times More Ink, Pocket Size, Fake Money Checker - Money Loss Prevention Tester & Fraud Protection for U.S. Currency (Pack of 1)

Dri Mark 351B1 Counterfeit Bill Detector Marker Pen, Made in The USA, 3 Times More Ink, Pocket Size, Fake Money Checker - Money Loss Prevention Tester & Fraud Protection for U.S. Currency (Pack of 1)

Q: How does the Dri Mark Counterfeit Detector Pen work?

The iodine-based ink reacts with starch in fake bills, turning dark. On real U.S. currency (starch-free), the mark stays light.

Q: Can it detect foreign bills?

Standard pens are for U.S. bills only. Dri Mark’s Universal Pen can check some foreign currencies but not polymer bills.

Q: Is it effective on old and new bills?

Yes, it works on all U.S. bills since they all use the same cotton-linen paper without starch.

Q: Can counterfeiters fool the pen?

Advanced fakes using real paper (like bleached bills) may pass. Use UV lights or other tools for better security.

Q: How long does the pen last?

It lasts long due to a larger ink supply. Keep the cap on tightly and store it cool and dry to maximize life.
