How does the Drimark Dual Test Pen work?

The ink test checks the paper quality by marking the bill—dark marks typically indicate fake bills. The UV light on the cap helps reveal embedded security features like watermarks and security threads found in legitimate U.S. currency.

What denominations or currencies can the Drimark pen verify?

Designed primarily for U.S. paper currency, from $1 to $100 bills. It is not recommended for use with foreign currency, polymer bills, or commemorative notes, as the detection methods rely on U.S. bill features.

How reliable is the Drimark pen for detecting counterfeit bills?

Offers a quick and effective way to screen for counterfeit money. When used correctly—combining both the ink and UV tests—it provides a reliable first line of defense against most fake bills.

Can the Drimark Dual Test Pen damage or mark real bills?

No, when used on authentic bills, the ink leaves a light or invisible mark that fades over time. It only leaves a dark mark on suspicious or counterfeit paper, helping to identify fake bills without damaging real ones.

How should I store the Drimark Dual Test Pen for best performance?

Store it with the cap securely on when not in use and away from heat or direct sunlight. Keeping the pen in a cool, dry place helps prevent the ink from drying out and preserves the UV light’s battery life.
