Normally I would say that you should help fund this Kickstarter project, but the Polar Pen, designed by Andrew Gardner of Waterloo, Ontario, has already received over $550K!
The Polar Pen is a really cool, innovative pen made up of 12 individual magnets. This allows the user to customize the pen to their liking–removing or adding magnets to make it either longer or shorter. It can also be customized with different colour cartridges and by attaching a variety of different tips, such as a stylus tip to use with tablets.
If you wanna grab one, you can get it here.
