## Questions & Answers

**Q: Does it have an interchangeable nib?**
A: thats a 2 part answer, the nib itself can be taken off yes; but we don't sell the whole nibset with the grip/feeder/feeder holder all together for that pen separately. But the nib itself is removable without the grip and feeder and holder. Yo can swap on any other Jowo made #4 size nib. Or buy one of our Diamond Mini nib sets, and swap on just the nib into the pen.
