Leonardo Officina Italiana is a forge, a laboratory where experience and craftsmanship are mixed giving life to “pleasure”, the pleasure of writing. Over 45 years of experience in the field of writing instruments, handed down from father to son, from generation to generation. Today Leonardo Officina Italiana works on emotional and vintage projects, taking up the old loading systems, the materials and the working techniques that once characterized the craft of the craftsman. The Leonardo pens have a soul, a human warmth that only passion can give. The fountain pen carved into the material is certainly this detail that differentiates us on the world market. Each Leonardo collection is hand made in Italy.
