Remember when you were a kid and you used to doodle with one of those 4-color Bic pens.  Well modern multi-pens are still extremely popular in Japan and as it turns out they are surprisingly useful in your grown-up day job. They are great for sketching diagrams in multiple colors, marking up documents with vicious redlines, or annotating TPS reports with color-coded passive-aggressive edits.  One of our favorites is the Platinum Double 3- Action Multipen which has both red and black balllpoint pens and a .5mm mechanical pencil.  It’s gunmetal grey body looks completely at home in the board room and the weight and mechanical action exudes precision.  If you want more colors, there is the Zebra Clip-On 1000 4-Color pen which features a hefty metal body, black, red and green ballpoint pens and a .5mm mechanical pencil.
