Fisher Space M4

Write at any angle, write upside down, write under water and through grease, write against extreme temperature (-30 to 250°F), write three times longer than any average pen, write on almost any surface and of course, in the gravity-free vacuum of space. With Cap-O-Matic Stylus Pen, the writing experience has no limitations. Retract the point and it becomes a capacitative stylus for all smartphones and tablet touch screens.
