At Porsche Design, innovation has always been at the heart of our design philosophy. Take the Shake Pen Twist, for example. The first model was released in 2006, and very soon the series became the most successful product in the Porsche Design Writing Tool collection. The reason for this popularity is an innovative feature: a short, sharp shake makes it ready to write and repeating the same movement retracts the ink cartridge. This and 50 other Porsche Design products that made history can be found in the ‘50 Years of Porsche Design’ coffee table book, recently published as part of our 50th anniversary.
