## Questions & Answers

**Q: Does the "good" Amber mark fade or is it permanent? Thanks for your help.**
A: You put a small "x" on the bill with the pen. If the "x" is a golden yellow color it is authentic and the "x" should fade. If it's counterfeit the "x" will stay black..hope that helps.

**Q: How long is the pen?**
A: Exactly 5 1/2” long

**Q: can this pen detect a foreign country currency**
A: You didn’t say what country.  I believe foreign currency banknotes (cash) are not all the same, so that would be a fat no.
