Once you've carried a pen around in your pocket or your bag for a few days, it becomes part of your life. You use it to make notes, get a few ideas down, make a record of useful things that have happened, and occasionally, stretch your creative muscles. In effect, this design is a tribute to the exceedingly analogue act of marking paper with ink.
