Porsche Design P'3110 Tecflex Ballpoint pen. Collector’s Edition with model car. Beautiful ballpoint pen by Porsche Design in good condition. This pen is available in a gift box with a miniature Porsche 997 Carrera S. Excellent performance in an instant: the Porsche Design Tec Flex mechanical pen is a unique expression of Porsche Design’s power, ambition and technical perfection. In motorsports, flexible, corrosion-resistant and wear-resistant qualities of braided stainless steel are used to protect sensitive electronic components. In the Tec Flex series, the same high-tech texture gives these ballpoint pens their exclusive look and charming features. When the button mechanism is activated, the decorated barrel is pulled together and released once the mechanical tip is out. All Porsche Design Tec Flex writing instruments are forged in virtually unwearying stainless steel. A high-quality replaceable rubber is hidden under the screw cap. For black/steel models, black resin threads intertwine with metal. In its original case with booklet. Photos are an integral part of this description, with box. Accurate and insured shipping.
