Visconti Homo Sapiens Lava Bronze Age Rollerball Pen

Made from basaltic lava sourced from the Mount Etna volcano in Sicily, the Visconti Homo Sapiens pen is virtually unbreakable, comfortable and warm to the touch, and slightly hygroscopic meaning it absorbs moisture from your hand.  The tips are made in solid bronze, and the pen cap use Visconti's 'Hook Safe Lock' system.  The fountain pen's vacuum power filler is made of titanium to resist ink corrosion.
