Porsche Design Shake P3140 Ballpoint Pen - Green - amazing Pocket Pen. I have a few of them. The one little issue was there is not a clip for this pen on the market, at least from my research!
I improvised and used a mag light clip that I will include. This item is in the category "Collectibles\Pens & Writing Instruments\Pens\Ballpoint Pens\Other Collectible Ballpoint".inc" and is located in this country: US. This item can be shipped to United States.
