The materials used in the Visconti Homo Sapiens Steel Age rollerball pen may be as old as the earth itself. Basaltic lava from the Etna volcano and a special resin are skillfully combined in a new patented process. The result is a dense, virtually unbreakable body. Unlike celluloid pens, the Homo Sapiens is essentially flameproof. Appointments are forged from marine grade stainless steel - no plating. Simple polishing will restore its natural beauty.
