The Homo Sapiens is handmade from hardened basaltic lava sourced from the Mount Etna volcano in Italy, with a trim made of solid bronze. Visconti lava is virtually unbreakable, comfortable and warm to the touch - and slightly hygroscopic, absorbing moisture from your hand. ÊThe pen caps using the Visconti 'Hook Safe Lock', a revolutionary capping system so you can cap a pen without worrying about the cap accidentally unscrewing in your pocket and leaking. The fountain pen's vacuum power filler is made of titanium to resist ink corrosion, and features a two-tone 23kt palladium extra-fine nib.
