Notebook that has size of Credit Card and Pen
A pen and notepad that are too small they fit in the credit-card slot in your pocket-book:
The credit card size, its slim cover contains a pad of 15 self-stick notes and a tiny pen with Flexigrip “wings” for a stable grasp. It fits easily in your wallet for instant access anywhere, and pop-up tabs on the top and sides make it easy to retrieve. (3 x 2″; 1 oz)

The company which makes that wallet notepad is called Picopad. They have a web site and a WMV [ed - ick] video clip which gives a good idea of its size and usability.
