- Made from volcanic lava rock, the pen is virtually unbreakable, naturally hygroscopic and very comfortable to write with.
- The cap closes with Visconti’s patented ‘hook safe lock’.
- Features the soft, buttery smooth Visconti 18kt gold fountain pen nib in white gold to match the color of the trims.
- Two larger steel-trimmed windows are cut into the pen’s barrel offering a view of stored ink in the larger ink reservoir.
- A smaller window behind the pen’s grip offering a view of stored ink in the pens second smaller ink reservoir.
- When ink in the smaller reservoir runs out, the user opens the valve to transfer ink from the larger reservoir to the smaller. Now the small reservoir is full of ink and the user can continue writing.
- Before air travel, the user does the opposite and drains ink from the small reservoir back to the large reservoir and then tightens the valve. Once empty, there is no ink in the small reservoir to leak out of the nib due to a change in air pressure when flying.
