Introducing the Visconti Homo Sapiens Lava Color Tuff Fountain Pen - a remarkable writing instrument handmade from hardened basaltic lava sourced from the Mount Etna volcano in Italy, making it virtually unbreakable and very comfortable to write with. The exquisite pen is made with a ruthenium trim and a 14K gold nib that provides an amazingly smooth writing experience with a high degree of resilience. The basaltic lava is mixed with resin to create this pen and the lava is flameproof and highly heat-resistant, meaning it can handle temperatures of up to 100°C. It's also slightly hygroscopic, allowing it to absorb hand sweat during use. The Homo Sapiens Lava Color is made with a combination of the high valued material and colored resin. This fountain pen also has a vacuum power filling system that is easy to use and has huge ink capacity. The Lava Color is the perfect addition to the Homosapiens collection and a must-have for every Visconti pen enthusiast.
