From TenOneDesign http://www.tenonedesign.com/sketch.php

This is the only stylus that works well with capacitive touch screens. Great to draw or capture signatures on your device.

Now Available in HOT PINK!!

This is the best stylus for taking signatures on mobile devices like the iPhone, or on Apple's new tablet.

Great for the iPhone, iTouch,iPad and Blackberry Storm

NOTE: If you are purchasing this stylus for your iPad, and don't have a case, consider the TenOneDesign Particle Case http://tenonedesign.com/particle.php which I sell and comes with a sketch and a holder built into the case so it's always attached to your iPad.

Superbly designed using a light-weight aluminum alloy and detailed graphics, the Pogo Sketch features a look that's hard to ignore.

The soft tip glides easily over the surface of your display, making it fun and easy to sketch, draw characters, or just slide to unlock. Sized for comfort, it does away with inaccuracies common to fingertip-only use.

Wear gloves in the winter? We do. With an iPhone, the stylus allows you to answer calls and surf the web all while keeping your hands toasty.

Longer nails can be a problem with touchscreen devices. Using your Pogo Sketch, you'll soon find that problem is history!

Lastly, the cool, glossy Pogo Sketch pocket clip will keep your stylus close by, wherever you are. If would want your stylus attached to your iPhone or Touch, order the Pogo Stylus instead.
