what ink fits this pen

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.

Can women use this pen?

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.

How does this pen open? Is it a twist of the cap to advance the cartridge?

It's a standard clicker pen. Really easy to use. You twist the endcap to replace the ink cartridge. It's a wonderful pen!

What is the barel of the pen made from, is it metal or plastic?

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.
