Pininfarina Stylus Cambiano Silver Luxury Edition. Pen made of Silver 925, exclusive "Leonardo da Vinci 500th Anniversary" collection. Pininfarina Cambiano Silver 500th anniversary is born from the union between the most modern technologies and the historical goldsmith craft experience of Vicenza. A stylus completely made of 925 silver realized through Additive Manufacturing, which consists in the fusion of successive layers of silver powder by means of a powerful carbon dioxide laser. This innovative technique has allowed us to create this Luxury Edition of Pininfarina Cambiano while maintaining its original design. The writing instrument is enriched on the surface with geometries explored by the master Leonardo Da Vinci and that we find in some of his studies on the squaring of the circle. Pen with a length of 16 cm delivered with original box and official guarantee. bf22
