## Questions & Answers

**Q: What color cartridges does this pen come with, and what brand(s) of replacement cartridges does it accept?**
A: It usually comes with blue ink cartridges.   I like black so I purchased lots of black cartridges.  I use Waterman Intense Black ink cartridges.  I have not tried other brands since I very happy with how the combination of the pen and ink works 🤗

**Q: Does this come with a ebonite nib? Or which kind?**
A: It comes with a plastic feed.

**Q: Do the cartridges that come with the pen contain ink or are they empty to be filled by the user?**
A: Ink cartridges always contain ink. It’s a matter of whether the cartridge is a standard international cartridge or a proprietary one.  I believe that the pen that you are referring to accepts standard international ink cartridges.   Most pens come with a converter that allows you to fill the converter from an ink bottle.  You can fill many converters with an eye dropper as well.

**Q: Does the nib and ebonite feed come apart from the pen housing? If so, how do you disassemble it? I'd like to clean the nib.**
A: It is friction-fit; the ebonite feed and the nib can be pulled out from the housing by direct force- preferably using a piece of rubber grip to avoid deforming the rather fragile ebonite feed. Note the slight asymmetry in the opening of the housing when re-inserting the nib and ebonite feed or else the internal wall of the housing may be damaged.
