Porsche Design's new Shake Pens will appeal to those who like a perfect balance of form and function. The pens house a mechanism that allow their ballpoint tips to retract and extend with a simple shake of the wrist.
The pens will cost north of $200 (for the black version), but the silver version will be a tad bit more affordable at $130.
