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.

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.

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.

Can counterfeiters fool the pen?

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

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.

Every seller’s new best friend

I sell my unused junk locally and take cash often. This marker makes it super easy to spot the fakes without awkwardly inspecting bills under a blacklight or squinting like I’m trying to read ancient hieroglyphics. It’s quick, reliable, and doesn’t damage legit money. Plus, it’s tiny enough to keep in my bra.
