CENTO3.G *** Archiproducts Design Award – 2021 WINNER *** Pocket fountain pen with a trilobed arch shape, made of graphene filaments and a chrome-plated metal mechanism. Each piece is individually produced using innovative 3D additive manufacturing techniques. The unique and complex arch design is extremely clean, ergonomic, and perfect for a three-finger grip. It features a pleasant tactile finish with excellent non-slip grip and a natural graphite color. Black ink cartridge included. Stainless steel Schmidt nib, medium point. Closed length: 10.3 cm Open length with cap: 13.5 cm Barrel diameter: 1.5 cm Weight: 23 g Material: Bio-based PLA polymer and graphene Production: Hand assembly, 3D printing Made in Italy Distinctive features of CENTO3 THE SEAM The visible stitching along the barrel certifies the slow and precise production of each piece, increasing its long-term value and showcasing high-quality 3D printing. Each artifact gains uniqueness from its own "scar," with the texture of the graphene filament, a pleasant touch, and a natural graphite finish. THE TRILOBOLO SHAPE: The trilobed cross-section prevents the pen from slipping on surfaces like round-section pens and provides an ergonomic three-finger grip. THE NAME CENTO3 marks the years from the birth of Achille Castiglioni (1918) to the public presentation of the writing project by architects Castiglioni and Cavaglià (2021).
