Cross Classic Century Lustrous Chrome Ball-Point Pen
If you need to carry a pen around from time to time, this is an excellent choice. It's slim body makes it easy to stash into any briefcase or pocketbook, while its sleek, chrome finish gives it a touch of class that most other pens can't match. It opens and closes with a smooth twist of the barrel, and comes with a (limited) lifetime warranty. Plus, it's around $20, so it's a good buy.
