EGOUNDESIGN presents CENTO3: a symbolic project born from the visionary mind of Achille Castiglioni—one of the most influential figures in Italian design. Conceived in 2001 and brought to life two decades later, CENTO3 merges timeless creativity with contemporary innovation, made possible by advanced 3D printing and a biobased graphene material. The CENTO3.O mechanical pencil features a distinctive trilobate ergonomic section and 0.7mm leads, offering precision and comfort for technical drawing and daily use alike.
