The hightech ball writing instrument is characterized by its innovative shake technology, echoing the piston action of the car. With a brief wrist movement, it is ready to write. Repeat the same motion and the refill "disappears" in to the barrel, which is available in caoutchouc, white resin, carbon or filigree milled aluminum. Nose and end pieces are chrome plated finished in matte or gloss. The weight and shape of the pen feel nice in the hand. Shake technology makes it easy to keep in your pocket. Choose from four styles.
