Uni-ball Jetstream 4&1 4 Color 0.7 mm Ballpoint Multi Pen + 0.5 mm Pencil - Bright Series - Green Body

AWESOME pen. I deliberated over buying the pen, but nothing beats having 4 ink colors (smooth-writing gel ink, no less) plus a pencil and eraser, all in one instrument. For meetings, noting things in my planner, etc. I just grab my trusty pen and go. Plus, it looks cool, so you make a better impression in meetings, interviews, etc. than you can with a 99-cent cheapo pen.

Downsides:
1. It's thick and grippy, which feels great in the hand but makes it unsuitable for my planner pen loop. Easily solved, though--I hang the pen from the loop by the clip instead.
2. Since I use this pen almost exclusviely now, I run through lots of inks. But they're pretty cheap on this site. I stock up!

I already purchased a black and white version in the past and it is the best note taking pen I've ever used. The colors are vivid and help separate important details that go unnoticed when I go back over my notes. The only thing I don't like about new versions is that the color of the cap does not match the barrel color. I wish the cap was black. Best multi Jetpens sells in my humble opinion. I prefer this over my sharbo x and at $15 I can afford a few of them and don't worry about losing them.
