The Visconti Homo Sapiens is crafted from basaltic lava sourced from Mount Etna, blended with resin for strength and a unique tactile feel. The solid bronze trim complements the lava’s slightly hygroscopic properties, absorbing moisture for a comfortable grip. The pen features Visconti’s 'Hook Safe Lock' to prevent accidental uncapping, and its titanium vacuum power filler resists ink corrosion. The gold-plated 18k gold medium nib matches the bronze trim, offering a smooth writing experience.
