Princeton Technologies based in Tokyo announced today the release of a new case and pen combination. This case and pen is only available in Japan but may be expected to ship internationally.

The case is made of sheepskin and is available in Black, Red, and Brown and comes with an interesting stylus. They claim the pen will not scratch the screen because of its unique rubber tip, also they have a spring loaded system to prevent you from pressing too hard on the Multi-Touch screen.

Because this is only available in Japan, people in other places have limited options. ThinkGeek has an iPhone stylus for sale for 24.99 and it works with the same principle. The iPhone only can sense your finger because of it uses a technology called capacitive touch which measures the flow of electrons through your skin. These pen somehow trick the phone or iPod Touch to think it is a finger and it will let you select on screen items more precisely.
