The Fisher Space Pen Matte Black Bullet with Stylus Ballpoint Pen is a matte black doppelganger to its smooth, chrome counterpart.

In addition to that the pens cap is equipped with a stylus tip that works on touch screen. Now carry the compact ballpoint anywhere and work it on paper or on touch screen as well.ATTENTION: The Stylus on this Space Pen has a hard nose. It will NOT work on iPhone/iPad/Android tablet/smartphone screens. If you would like a stylus to work on those screens, please check out the Fisher Space Pen BG4S.
