Visconti is pleased to announce the new Homo Sapiens 'Dark Crystal', the latest addition to Visconti's iconic Homo Sapiens series.
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 Crystal 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 pens body and replaced with a piece of smoky acrylic tube, transforming the pen into a demonstrator with a unique appearance and identity. This 'oversize' window offers the user a view of stored ink inside the pen and the pens '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 pens grip section. Metal has been replaced with smoky acrylic resin, offering a view of stored ink in the pens 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.
Available as a fountain pen only, featuring Visconti's buttery smooth, in-house, 18kt gold nib in black to match the color of the pen's trims, available in EF, F, M, B, and Stub.
Nib Material: Ruthenium coated 14k Gold
Filling Mechanism: Double Reservoir Power Filler

Perfect Keto-Friendly Gum, Clean Ingredients & Great Flavor!
Flavor Name: Spearmint, Size: 55 Count (Pack of 1), Flavor Name: Spearmint, Size: 55 Count (Pack of 1)
I’ve tried so many sugar-free gums, and this is by far the best option for anyone following a keto or strict carnivore lifestyle. It’s aspartame-free, has clean ingredients, and doesn’t leave that artificial aftertaste that most gums have. The spearmint flavor is fresh and long-lasting, and I love that it helps satisfy cravings without adding sugar or unnecessary carbs.
The texture stays soft longer than other brands, and the resealable bag is super convenient for keeping in the car, gym bag, or at work. If you’re looking for a healthier gum that fits perfectly into a low-carb, keto, or carnivore-focused routine, this is definitely the one to buy. Four stars only because the flavor only lasts about a minute.

Good alternative to traditional gums- no aspartame no artificial coloring.
Flavor Name: Spearmint, Size: 55 Count (Pack of 1)
Love this gum, no aspartame, no artificial coloring and good taste, you get used to chewing it for a long time, the taste goes away little faster than traditional gums but I don't care

Great Xylitol Chewing Gum!
Flavor Name: Spearmint, Size: 55 Count (Pack of 3), Flavor Name: Spearmint, Size: 55 Count (Pack of 3)
This review is for PUR Gum | Aspartame Free Chewing Gum | 100% Xylitol | Natural Spearmint Flavored Gum, 55 Pieces (Pack of 3). I got 2 of the 3-pack at the time because it was cheaper to do so than to get a 6-pack. Of course, the next day the 6-pack was cheaper lol. Anyway, this is great xylitol gum and not overly expensive like Zellie’s. I take 2 (which is one serving meaning 2g of xylitol) after “most” meals because it’s supposed to be good for my oral health. I chew one piece at a time for a couple minutes to prolong the sweet flavor instead of popping both into my mouth together. I like chewing these because they don’t harden up like some gums do. They stay soft throughout and I often forget and chew them for 15-20 minutes at a time. Anyway, I did the math and compared the PUR gum to other 100% xylitol gums out there and this one was a clear winner to me for the same benefits. I would totally recommend this gum and I like that it’s aspartame free! I’d give it a 5.0/5.0 - 03/20/2026.

Great taste but cannot use
Flavor Name: Spearmint, Size: 55 Count (Pack of 1)
First time trying for dental care. Really enjoy the taste only drawback taste doesn’t last long. However, it’s better than other sugar substitutes which my stomach does not like.
Glad I signed up for the three pack sub. Great product! Recommend.
May 16, 2026 Update: Unfortunately I cannot use this product after the initial trial every time I chew on these i experience stomach issues so the three pack I purchased will need to find someone that can use them or throw out.

Powerful lasting peppermint flavor & the xylitol fights plaque!
Flavor Name: Spearmint, Size: 55 Count (Pack of 6)
The gum has a powerful peppermint taste – very refreshing. The flavor lasts a long time. The main reason that I bought this gum is because it has 100% xylitol. Xylitol helps fight plaque buildup. I have only had the product one day, so I can't say that it works, but I read many reports before I bought the gum that xylitol is excellent for fighting plaque buildup. It also has no sugar. It's vegan and it has only five calories per two pieces. I have so far only chewed one piece at a time. One piece seems plenty for me. I've read that people need from six to ten grams of xylitol per day to effectively fight plaque. So, this gum needs to be chewed accordingly. Many people chew after every time they eat. I am happy with this purchase.
