## Questions & Answers

**Q: Can you change the batteries of the black light?**
A: I don't think so.  These pens are so cheap the battery would probably cost more than a new pen!

**Q: Do they have  enough  ink to last long?**
A: Your question depends on the user - my guess is, the ink will last about as long as any other thin tipped felt pen.  If you're planning to use these as security measure against fraudulent returns, its more likely you'll leave the cap off sometime over the next year causing the pen to dry out, long before it would run out from use.

**Q: How bright does it show up**
A: Not very bright in my opinion.

**Q: How big are they?**
A: Each pen, including the light on top, is about 5 inches long.  It's about as thick as a standard "stick" pen, but the top (about 1 3/4 inches) with the light in it is wider, maybe a half inch in diameter.
