The Homo Sapiens Dark Crystal is 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.

An update to my favourite pen

After purchasing my first homo sapiens, a bronze age, from the Goulet Pen Company before an overseas deployment many years ago, I sadly lost it to a car accident in '21. After finally deciding to replace it and reviewing the current Visconti lineup from Brian's shop, I finally have replaced my all time favourite pen with the dark crystal model and could not be happier with this pen. I have always loved the hygroscopic nature of these pens as my primary reason of purchase, as they are the only pens I can write for hours without losing any grip due to sweat or skin oil.

Perfect

I wouldn't hesitate to buy from this seller again. Very satisfied indeed.

Quality Control Issues

Pen had a few red flakes on it very disappointed that this was not caught by QC at Visconti, or Goulet (who I asked to check the pen). My 1st HS pen had a uniform lava finish.Good, but not great, customer service (every little thing required manager approval), poor shipping options. Not the best first experience

Not happy.

Nib is scratchy and it leaks from the feeder. Beautiful pen, but not happy with this one piece

Good, but QC issues

5/5 writing experience, minus 2 stars for nib issues. I received the medium nib with misaligned tines and had to fix it myself. At this price point, everything should be working without issue. I have the knowledge to fix misaligned tines but imagine if you didn't and/or are unwilling (scared to damage the pen etc). Then what? The pen can't write. Then you'd have to go through return/exchange process and a long wait time for shipping. Just putting my experience out there for buyers looking at this pen. Final note - I do like the pen a lot though as it writes very well after fixing the nib alignment issue.

FAQs about Fountain Pens

How do I fill a fountain pen with ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the pen's filling mechanism, which you can find in the Technical Specs section above. 

Here's a quick definition of the most common filling mechanisms:

  • Cartridge - A small, disposable, sealed plastic reservoir that holds fountain pen ink. These come pre-filled with ink, and typically you just push to insert them into place and you'll be ready to write! Check out our quick guide here.
  • Converter - A detachable and refillable ink reservoir that allows you to use bottled ink in a cartridge-accepting pen. Typically you will install the converter into the grip section, dip the nib/feed into the ink, and twist or pull the converter knob to draw ink into the converter. Here's a video for how to fill a cartridge/converter pen using a LAMY pen as an example.
  • Eyedropper - A pen that utilizes the entire barrel as a reservoir for ink. Ink is directly filled into the barrel, allowing for a high ink capacity. Here's a video on how to do it!
  • Piston - A type of filling system that uses a retracting plunger inside a sealed tube to draw ink into a pen. They are typically either twist or push-operated. These pens cannot accept cartridges or a converter, and only fill from bottled ink.
  • Vacuum - A push-style piston that uses pressure to fill the large pen body with ink. They seal the ink chamber when closed, making it ideal for flying without risk of leaking. Check out our video on how to use a vac filler here.

Check out more info on these filling mechanisms including a video on how to fill each one on our blog.

How do I clean a fountain pen? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the filling mechanism, but it mostly comes down to flushing it out with water, and sometimes a little bit of Pen Flush if the ink is really stuck. 

It's a bit easier to show than to tell, so we've put together a few quick videos showing you the process:

How often do I need to clean my fountain pen? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

We recommend a good cleaning every 2 weeks, and any time you change ink colors. 

Water will usually do the trick, but we recommend you use our Goulet Pen Flush if the ink has been left in the pen for a while and could have dried up, or when you’re switching ink colors.

My pen won’t write! What do I do? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

First things first... make sure you have ink in the pen! Be sure that the ink cartridge or converter is seated properly in the pen, and that you aren't out of ink.

We always recommend you give your pen a good cleaning first, using our Goulet Pen Flush, or a drop of dish soap in some water. New pens often have some machining oil residue left in the feed, so a good cleaning often does the trick first.

If that still doesn't work, try priming the feed. This consists of either dipping your pen nib and feed in ink, or forcing ink from the converter down into the feed. 

If it’s still not working after that, please reach out to us so we can help! 

What's your return policy? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

You can submit a return request within 30 days of your order date. You can read all our Return Policies here.

To initiate a return, please submit a request at the Return Portal. Our Customer Care team might reach out to you for more information.

Please note we are unable to accept a return of any Namiki or Sailor Bespoke fountain pen for any reason once it has been used with ink. Please thoroughly inspect and dry test the pen before use.
