## 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.

### ⭐⭐⭐⭐⭐ BEAUTIFUL RAW BRASS PEN
*by K***N on January 19, 2025*

Just got this in the mail today! I can’t speak of longevity of it . However I can give you my initial thoughts.. great presentation packaging! Upon opening the RAW BRASS pops , absolutely beautiful pen! I have it here in the video next to my solid brass zippo for “somewhat of a comparison” The construction of pen seems to be of great quality! Although it is a little lighter than I thought it would be .. not necessarily a bad thing . I would say weight is good! It screws on and off to get to the refill with no hesitation. Clicking the top part of pen does not feel mushy as some others have said .. I clicked it in my video and you can see and hear the responsiveness of it . Writes very nicely! No complaints here! I would buy again and recommend to a friend! I will update as I use it more! Please note I’m a truck driver / laborer and very very hard on my pens.. I will update!
