Experience the unparalleled power of the Visconti Homo Sapiens Lava Color Terra Di Siena Fountain Pen. Handmade from hardened basaltic lava sourced from the Mount Etna volcano in Italy with a ruthenium trim, this pen is truly unique. The basaltic lava is mixed with resin to create this pen and its 14K gold nib provides an amazingly smooth writing experience. It is flameproof, and has a resistance to heat of over 100°C, making it very resilient. Additionally, its slightly hygroscopic quality allows it to absorb hand sweat during use, making it comfortable to write with. The process of catalyzing the lava material with coloured resin is very complex but the final look of the writing instrument is unique and makes the collection stand out from other Homo Sapiens editions. This new edition also has an anti-stain treatment that protects the pen and prevents ink from depositing on the pen during the refilling phase. The Lava Color is the perfect addition to the Homo Sapiens Collection, featuring a power vacuum filling system that is easy to use, while its volcanic lava construction makes it virtually unbreakable. The pen also has a magnetic lock closing system which makes opening and closing it effortless. A must-have for every Visconti pen enthusiast, the Visconti Homo Sapiens Lava Color Terra Di Siena Fountain Pen is the perfect blend of form and function.
