## Questions & Answers

**Q: How does the Dri Mark Counterfeit Detector Pen work?**
A: 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?**
A: 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?**
A: 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?**
A: 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?**
A: It lasts long due to a larger ink supply. Keep the cap on tightly and store it cool and dry to maximize life.
