I found some pocket pens today in my quarterly (ok more often than that) Staples prospecting trip for prodnography. These pens are the Staples brand, and although I can't find them on the website, the item number is #636172. The pens are black gel ink and have caps which help to make the pen a comfortable length while writing. They have a clip, which works incredibly well parked on the top of a 3x5 flip-fold notepad. Best part about it - you get 12 for $2.99 - at 25 cents per pen, my proclivity for losing small pens is now no longer an issue!
