    I always need a pen and can never keep one in my pocket so this comes in real handy

    2nd most useful insert, writes well and surpringly smooth! Well done.

  9. Paul H. (verified owner)

    Good pen.
    Stopper allows it to hold its position against the Keybar frame as you write – nice design touch.
    Would like to see next version allow refills.

    Really awesome. I’ll never again have to say “damn, I wish I had a pen with me.”

    Picked this up so I would always have a pen on me for geocaching without adding too much extra to my pockets. Works great.
