The Homo SapiensDark Crystalis an exceptional fountain pen, showcasing all of the unique benefits of the original, award-winning Homo Sapiens with several upgrades and modifications:
Smoky Ink Chamber: The most discernible modification to the body of the pen is the addition of a large transparent window made from acrylic resin. A large section of lava has been cut out of the pen body and replaced with a piece of smoky acrylic tube, giving the pen a unique appearance and identity. This 'oversize' window offers the user a view of stored ink inside the pen and the pen's 'double reservoir' power filling system.
Double Reservoir: The original Homo Sapiens featured Visconti's 'single reservoir' power filling system. The Dark Crystal is upgraded to Visconti's patented 'double reservoir' power filler, a vacuum filling system that is easy to use and has considerable benefits. Patented in 1998, this is arguably the most advanced filling system ever developed in fountain pen history. The user is able to fill the pen with the equivalent of 10 cartridges of ink, and thanks to the two reservoirs, prevents ink from leaking during air travel.
Smoky Crystal Ring: The final change is the small ring around the grip section. Metal has been replaced with smoky acrylic resin, offering a view of stored ink in the pen's second smaller ink reservoir.
As with the original Homo Sapiens, the Dark Crystal is made from volcanic lava rock, making the pen virtually unbreakable, naturally hygroscopic and very comfortable to write with. All trims are made from steel with ruthenium plating and the cap closes with Visconti's patented 'hook safe lock'. The Homo Sapiens Dark Crystal is a must-have for every Visconti pen enthusiast.
The 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 double reservoir vacuum power filler is made of titanium to resist ink corrosion, and it features a ruthenium-plated oversized 18k gold nib to match the trim color.
