## Questions & Answers

**Q: Can you use it in a fountain pen?**
A: Do not use this ink in a fountain pen. This ink has pigments - think of tiny granules of pigment suspended in water. Those granules will clog a fountain pen feed over time. True fountain pen inks have no floating particles. This ink is for dip pens (no ink reservoir, just dip and write) or brush painting only.

**Q: Can this be used on smooth bristol paper? I read that sumi ink only adheres to rice paper, but I'm not sure about the validity of that claim.**
A: Well, I've used it on smooth bristol paper, as well as a number of other types of paper and had no problems at all when it comes to the ink adhering to any of them.

**Q: Can this ink withstand erasing?**
A: Light erasing, yes

**Q: Can i put this in a bingo dabber ? and use for poster boards? also if i paint over it would it seep through ?**
A: I wouldn't put it in a dabber for Bingo. It's Chinese liquid stick ink.  You want something that is water soluble. Depending on the paint over ink, it might seep through.  Mainly a calligraphy/drawing ink.
