## Questions & Answers

**Q: Does the pen tip turn color after the first several uses? Mine went from yellow to purple.**
A: Mine's half of the tip turned from orange into purple the first time I used it. Some say it will fade back over time while others say it's permanent. I don't know about validity of readings but I suppose they should still be consistent.

**Q: can this be used on fabrics?**
A: Sorry, it cannot. It only can be sued on paper or paperboard products. Thank you.

**Q: Would this work to test stickers?**
A: I haven't tried it specifically on stickers, but it has worked on all the various surfaces I have tested so far.

**Q: Will this work on black paper**
A: I'm not sure that it would, but I haven't specifically tried it on black paper.
