## Questions & Answers

**Q: Does it work in fountain pens?**
A: I have used it in calligraphy pens and as long as they are in regular use things are fine. Don’t leave them unused for any length of time as the ink is waterproof so therefore “sets” in the ink channels and cleaning is time  consuming but not impossible. Fountain pens will be the same, don’t leave the pen unused for too long or the ink will set in the channels. Scoosh the pen through with warm water to rinse out and all will be well.
