LAMY's “Pico” pen is one of the more interesting ballpoints I've seen, thanks to the clever push mechanism designed by Franco Clivio. Clicking the button not only pops out the writing tip, but also telescopes the back of the pen body, turning it from a nondescript little cylinder (3.5") to a full-length writing utensil (4.75").

Pictured here is the Chrome edition.

The Laser Orange shown at the top of this post is my favorite color because it's so bright and eyecatching, but there are others to choose from as well, like the more subdued Imperial Blue.

Whatever color you go with, this is a pen that would do James Bond proud. It fits nicely in your pocket when you're not using it, and then like a quick-change artist, shows its full potential when expanded. Very cool.

Get the Laser Orange Pico pen for $40 on Amazon. All versions of the Pico accept M22 Black M (medium) ballpoint refills.
