Description

Gravitas Pens introduces the Vac 2.0 Aluminium Black, a refined evolution of the acclaimed UltemateVac platform, engineered for writers who demand precision, capacity and full serviceability in a modern fountain pen.

The Vac 2.0 retains the core proportions of its predecessor while introducing subtle refinements in weight and balance. Its body is constructed from a mix of Ultem and anodised aluminium, paired with stainless steel PVD-coated section elements that add a satisfying, nib-forward weight for enhanced writing control. A double reservoir-ink window provides clear visibility of ink levels, while the cap featuring a  inner Delrin sleeve with ACME threads improves sealing and posting stability for a more secure writing experience.

At the heart of the system is Gravitas’ downsized Kraken filling mechanism, available  in the Gravitas - Monster, delivering an exceptional ink capacity of 4.5 ml+ (one plunge = 3ml ink / a double plunge = 4.5ml max capacity). This high-volume reservoir is designed for extended writing sessions with minimal interruption, making it ideal for both professional and creative use.

The fountain pen features a Gravitas newly developed proprietary #6 steel nib available in EF, F, M and B widths. It eliminates the traditional breather hole and incorporates a longer cut slit for a unique balanced feel in use, softer and with more spring than regular steel nibs. The newly developed nib is not a flex option, it's delivering the best performances in normal use without added pressure. The proprietary steel nib uses a custom ABS housing and feeder, while remaining compatible with standard* Jowo #6 formats.

One of the defining innovations of the Vac 2.0 is its fully disassemblable construction. The section can be unscrewed and the filling system can be removed using a dedicated maintenance spanner tool marked “Vac” allowing users to easily clean and lubricate the mechanism. This ensures long-term reliability and effortless upkeep, an essential feature for high-performance writing instruments.

Designed for both durability and engineering transparency, the Vac 2.0 Aluminium Black blends industrial aesthetics with functional sophistication, making it a standout addition to any fountain pen collection.

The smoothest pen I own!

The Vac 2.0 is hands-down the smoothest writer I have. The pen arrived with the nib tuned to perfection, with exquisite machining of every single component. The capacity is massive, yet the pen does not feel overly bulky. The balance in the hand both posted and unposted is right on. You can really tell that Ben pays the utmost attention to even the smallest detail!
Shipping to Australia was very quick and the order arrived with a wonderful hand-written note from Emy. This will certainly not be my last purchase!

Another Great Gravitas Pen

I ordered this pen even though I’ve had some issues with two of my six Monster pens—which amounts to a failure rate of nearly 30%. One of my Monsters (black aluminum) suddenly started leaking after three months of regular use (with Artisan Pastellier Rose Cyclamen ink; it still leaks in small amounts, even though I haven’t used that ink in it for months and am now using the fountain pen with GvFC Viper Green; otherwise, the pen works reliably). Unfortunately, two service requests regarding this issue went unanswered.

The other one (TiSinX titanium) is now, unfortunately, completely unusable, as every time I fill it, large amounts of ink immediately ooze out in thick drops from the same spot (though this could be due to using Diamone Desert Rose—I didn’t initially know that such inks might cause problems). I may contact Pen Venture at a later date regarding the purchase of a replacement ink reservoir (if possible with Ultem).

I haven’t had any problems so far with the Ultem Monsters or the Gravitas Exclusive Rainbow Skittle Monster.

The Vac 2.0, which is what this review was actually supposed to be about, is another great pen. Unfortunately, the Diamine Lady Grey ink I bought along with it seems much too dry for this pen, so I screwed in the gold nib from my Gravitas x Kyuseido Kakari, and now it writes like a dream; ironically, the original nib now writes just as beautifully in my Ultemate Vac - so I guess I have to review the new steel nib separately.

The Kraken filling mechanism works extremely well again and feels almost a bit more powerful in this pen than it does in the Monster; and the new ink window is a joy as well.

It's extremely well balanced and although I very much enjoy the girthier (and heavier) monster, fast note taking is kind of more comfortable with this pen—although, purely for aesthetic reasons, I actually like the flat ends of the Monster a little better.

However, there’s a minor flaw (which definitely isn’t due to the new gold nib, since it also occurred with the original nib) that happens when the ink reservoir is full and you screw the Kraken mechanism shut. Sometimes a large drop falls onto the paper then, but I suspect this can be prevented by simply not letting the reservoir get completely full.

That aside, the pen is a pure delight.

The broad nib I orderd it with is pure delight as well. It's nicely soft and writes very consistently with my (fairly standard, I guess) 50° writing angle. The line width is very consistent, which is a nice experience, given that many broad nibs these days have stub-like characteristics. Interestingly, this nib has this kind of character when using it in reverse for very, very small margin notes—something I haven't come across before with round-ground nibs. I kind of like it.

All in all another great and beautifully designed pen - but only time will tell if it's prone to the same problems as some of the Monsters.

The ordering process and shipment was smooth and seamless as always with pen venture and I received my ordering within just a few days. Emy added a kind handwritten note, a Monster maintenance tool and vial of silicon oil.

That creates a kind of personal shopping experience—which is something, also given that the store appears to be expanding quite rapidly.

Gravitas Vac 2

The construction of the Vac 2 is flawless. The textures of the materials and it's simple lines display an elegant beauty. The large steel nib delivers a pleasant writing experience and also provides a bit of flex.

Amazing Pen! Gravitas makes one of the best piston fillers out there. I dont keep the nib and normally use the pen for coustom flex nibs with Jowo #6 compatible nib units. So, i really cant speak on the nib. However, this pen is just built with high quality components. The weight, feel, and overall aesthetics are unmatched. You wont find better at this price point.

FANTASTIC!

The VAC 2.0 is a great improvement to an already great pen (the original VAC Ultem). The weight and balance are spot on. The cap and the new threads engage without hesitation. No missed closures and the cap has a nice stop when threading back on. It posts securely without issue. Filling with the Kraken system is easy. I got a medium nib and it is smoooooooth. Mine is on par with my 823 medium nib The smoothness, wetness and bounce would make you think it's a gold nib. Line width is slightly narrower than the 823 medium. The pen feels solid and well built. I'm not worried about this one getting knocked around. Overall a great pen. Shipping from Pen-Venture to Colorado was five days! Great pen and service all around!

If the Monster and the Vac 1.0 had a Love Child...

...this would be it! To be completely honest, the Monster's DNA is clearly the dominant factor in this creation! As a matter of fact, it might be more accurate to call this pen the Baby Monster, instead of "Vac 2.0". There are only a few characteristics of the Vac 1.0 that were passed on, such as having an Ultem ink window on the secondary ink reservoir. Speaking of which, shouldn't the "Primary" ink reservoir be the one that connects directly to the nib unit? The back up, or reserve reservoir should be the "Secondary" reservoir, since it feeds the primary reservoir, not the nib unit, but...whatever. Other characteristics inherited from the Vac 1.0 are the conical finials on the cap and barrel, as well as a #6 size nib. Ink capacity of the Vac 2.0 is more than the Vac 1.0, but less than the Monster; at 4.5 ml, it's more than enough to get you through an all night session of writing, maybe even all week!
The nib...unlike other Gravitas nibs, doesn't have a breather hole, and the slit is longer. The metal also may be thinner than other Gravitas #6 nibs, which in combination with the longer slit, may give this nib a bit more flexibility. My nib is very smooth! Ink flow is a little bit less than the Monster's, but more than the Vac 1.0's, and is consistent and predictable with Pelikan 4001 Royal Blue ink.
Fun fact: the ink uptake hole (where ink goes into the pen when you fill it) is located on the underside of the feed, pretty close to where the feed disappears into the grip section. It's like that with almost every fountain pen that's designed to suck ink out of an ink well/bottle. The only one I know of that has the hole way forward toward the tip of the nib is the Lamy 2000. How does that affect you? The farther the nib sticks out from the grip section, the higher up that hole sits from the nib's tip, and the more ink needs to be in the bottom of the ink well to make sure that the pen sucks up ink, not air. The #6 nib sticks out about 7/8" (22mm), the #8 nib (of the Monster) sticks out about 17/16" (27mm). So, unless you plan on transferring your favorite ink into tall, thin ink bottles (like Robert Oster ink bottles), use an ink miser or ink sample bottle, or get creative with an ink syringe, the smaller sized nib of the Vac 2.0 allows you to get more ink out of your bottle before the rest becomes unreachable. With a little patience, practice, and an ample supply of paper towels, you can fill almost any piston filler or vac filler with an ink syringe as if the pen was an eyedropper filler, as long as you can remove the grip section and squirt the ink directly into the barrel. Some pens won't let you remove the grip section, but you can unscrew the nib unit, which will also give you direct access to the ink chamber(s). Vac fillers are more difficult to fill like that, because the piston has to be pushed all the way forward, and then retracted just far enough to allow ink to flow around and behind the piston to fill the ink chamber. If you were to fill it with the piston all the way in the back, you'd just expel all of the ink as soon as you push the piston forward again.
I love that Vac 2.0 has a second ink window, which lets me know when I need to open up the big ink chamber to allow ink to fill the little in chamber. I love the smaller nib, which allows me to better access to ink in bottles that are less than half full. I love how smooth the nib writes, and that the line width is actually pretty close to the nominal "Fine" standard (0.3mm, +/- 0.1mm). I love that the cap and pen body are now mated with titanium threaded parts, with ACME threads, so there isn't the constant feeling of cross threading the Ultem plastic, like every time I put the cap back on my Vac 1.0. I'm still careful whenever I screw the cap on any of my pens, regardless of material or brand, but I'm extra careful with threads on my non metal pens.
So, if like the Vac 1.0, you're going to love Vac 2.0, because I believe all of the Vac 1.0's shortcomings were addressed. If you thought you might like the Monster, but thought it's too big or pricey for you, the Vac 2.0 is the perfect fit. Still more ink capacity than most fountain pens, including many dedicated eyedropper pens, yet almost the same size as a regular full size pen. Robust construction, high quality materials, flawless fit and finish.

Great pen. Love the Titanium, writes great, a tad heavier than expected but comfortable. Attachment of the clip is quite ingenious, if only we could have this clip on the Quarks (Message to Ben)

Right out of the box, the pen is an absolute stunner. Leonardo makes phenomenal writing instruments, but buying one through Pen Venture makes the ownership experience truly elite. Thank you, Emy and the team! This won't be my last Leonardo pen from your shop.

I love this pen! It writes great, looks great and feels great! Much more convenient for my small hands than the Monster. A terrific buy!

Gravitas - Quark Zirconium Stone Washed Pocket Pen | New |
Jamie Rees
The perfect pocket pen!

I'm typically not a pocket pen person, but as a worker in the nuclear industry, the allure of zirconium was too great to resist. I had nothing to worry about, as the pen is perfectly balanced when posted and very similar in feel to my trusty Fisher Space Pen, with slightly more heft.
The extra-fine nib arrived wonderfully tuned with just the right amount of feedback and when eye-droppered, the flow is juicy without being too wet.
Plus, that zing really is unique and worth the price of admission by itself!
