Description The Homo Sapiens Crystal Dream is an outstanding fountain pen, that takes the best of the unique benefits of the original, award-winning Homo Sapiens and adds a few upgrades and modifications, including a crystal ink chamber, improved double reservoir, and crystal trim ring. As with the original Homo Sapiens, the Crystal Dream is made from volcanic lava rock making the pen virtually unbreakable, naturally hygroscopic and very comfortable to write with. All trims are made from natural bronze and the cap closes with Visconti's patented hook safe lock. The Homo Sapiens Crystal Dream is a must-have for every Visconti pen enthusiast. Changes: The new Crystal Ink Chamber: The most obvious modification to the body of the pen is the addition of a large transparent window made from crystal clear acrylic resin. A large section of lava has been cut out of the pen barrel and replaced with a piece of clear crystal acrylic tube, transforming the barrel into a demonstrator with a unique appearance. This oversize window offers the user a view of the ink inside the pen and the double reservoir power filling systemUpgraded Double Reservoir: The original Homo Sapiens fountain pen featured Visconti's single reservoir power filling system. The Crystal Dream has been upgraded to Visconti's patented double reservoir power filler - a vacuum filling system that is easy to use and holds an enormous amount of ink. Patented in 1998, this is arguably the most advanced filling system ever developed in fountain pen history. You can fill the pen with the equivalent of 10 cartridges of ink, and thanks to the two reservoirs, prevents ink from leaking during air travel.The new Crystal Ring: The final change to the Visconti Homo Sapiens Crystal Dream is the small ring around the grip section of the barrel. Metal has been replaced with crystal acrylic resin, offering a view of stored ink in the pens second smaller ink reservoir.You can also customize this pen with the magnetized MyPen System. Choose from letters or natural stones that you can swap into the finial in place of the Visconti logo coin.
