## Questions & Answers

**Q: How big is the tip of this size?**
A: It's about the size of a normal Sharpie. It's not fine but also not wide. I've found I can get corners done by getting close and letting the color sort of bleed into the corner.

**Q: Is this a paint marker?  I need to write on black plastic.**
A: Yes it is a paint marker that marks and flows on just about anything. Best markers I have ever used and does not dry out or clog like most do. Even good on a rock!

**Q: Can anyone tell me the size point for outlining. Smallest point Posca makes?**
A: Extra fine. 1 M. Still not super fine, but it's the smallest they make. I use it for rock painting and it's awesome for outlining.

**Q: Will this paint be waterproof on glass so it doesn't wash off in rain or snow?  I want something that needs to be scraped off if I want it gone.**
A: yes water proof.
