Porsche Design’s automotive origins influence every detail of its range of accessories—from the materials selected to each item’s sleek look. Its writing tools are no exception: the P’3130 Mikado Mechanical Pencil is fitted with 17 polished metal rods; the P’3110 TecFlex Ballpoint Pen features braided stainless steel and the same TecFlex oil tube one might find under the hood, used in high-performance engine construction. That’s not to say these functional details don’t add a little fun to the form: watch the stems twist as you extend the point of the Mikado, and the TecFlex’s woven steel compresses with the click of a button.
