The Porsche Design ShakePen is a new high-tech design pocket ballpoint pen. A particularly impressive feature is the innovative ┬Źshake technology: A short, quick flick of the wrist causes the cartridge to extend or retract.  The cap top shows the Porsche Design logo. There is no clip - this is a small pocket pen, making it the perfect travelling companion.  A projection on the end cap prevents the pen from rolling away.
