## Questions & Answers

**Q: what ink   fits this pen**
A: Fischer Space Pen refills fit the pen.  If I use a space pen every day, I will need to get a refill about once per year, but your mileage may vary depending upon use.  I usually pick up a black refill ar Staples.  If you go to spacepen.com, you can order the following refills:  - Medium width ink - Blue, black, red green, burgandy, purple, brown, turquoise, silver  - fine ink - Blue, black, red, green  - bold ink - blue, blackRefills are $6.  There are space pen refills will fit Parker pens with the included adapter.  They also have Cross type refills.

**Q: Can women use this pen?**
A: I laughed when my wife asked if she could use this pen, and she responded by showing me how the pen would look if I were Frankenstein with a pen through my neck....

So, yes, women seem to be able to adapt quickly to this pen.

**Q: How does this pen open? Is it a twist of the cap to advance the cartridge?**
A: It's a standard clicker pen. Really easy to use. You twist the endcap to replace the ink cartridge. It's a wonderful pen!

**Q: What is the barel of the pen made from, is it metal or plastic?**
A: The entire barrel (end-to-end) is metal, but not magnetic, and it appears to be BRASS. The internal spring (magnetic) is steel. The internal mechanism appears to be white plastic.
