Description

Introducing the updated Quark Zirconium pocket fountain pen that redefines compact convenience without compromising on performance. The new Zirconium Quark still maintains its use of zirconium for the cap, body and section featuring the same satin texture having a unique tactile feeling. Different from the first version, the new Quark Zirconium sports a blacked-out section, new ACME threads making it easy to post and securely capped without having the need for a rubber o ring.

Crafted to be the tiniest pen of its kind, the Quark transforms into a full-sized writing instrument when posted. Its lightweight design and ergonomically weighted section ensure a comfortable and effortless writing experience.

Featuring double-start cap threads, the Quark effortlessly unveils its nib with just 0.6 turns. When posted, the cap securely threads onto the back in a mere 2 turns. The 22mm-long section, ranging from 9.85mm to 9.0mm in width, is precision-engineered from zirconium material with micro-machined grooves for added grip.

Equipped with a Gravitas-production size 6 steel nib - silver color, compatible with Jowo No. 6 threads and abs plastic feeder, the Quark offers versatile writing options, including Extra Fine, Fine, Medium, Broad and Fine Flex.

This pen is eye-dropper friendly, capable of holding up to 1.5ml of ink or a standard international ink cartridge. Every Quark includes a complimentary attachment, designed for conveniently securing your item to a lanyard or any carrying accessory, ensuring ease and comfort in your collection.

Elevate your writing experience with the Quark Pocket Pen – where compact meets functionality.

Quark, xf

Skipped so much I had to replace the nib unit with parts from my storage. Quite disappointing. The cap now screws on, I preferred the slip cap. It's faster. It's working now but I won't be spending any more money on gravitas.

Love the "zing"

To be fully honest, I bought the pen for the interesting material and for the awesome sound it makes. Ordered it in broad and as expected, it's a pleasure to write with. Will carry with it daily to impress and annoy my friends at work :)

Perfect for even the tiniest pocket.

I picked up the Quark Zirconium with a fine nib to act as a counterpart to a Pocket Zirconium and ended up enjoying this tiny pen quite a lot more than I had expected to. While I typically gravitate towards medium nibs, I felt like the Quark was a perfect time to opt for a fine, and it made quite the impression.
I admittedly still prefer medium nibs for day to day use, I appreciate having the option to write just a bit finer And with the Quark, that option is always just a couple of seconds away. The threads for capping and posting are easy to start and feel very secure.
Then there's that splendid ringing you can get out of this little pen. It's something so simple but it always brings a smile to my face.

A good pen as well as good customer service

I don't think I can edit my previous review but I will explain the context briefly. When the Quark arrived it was just as I expected except for an odd issue where the nib was inconsistantly feeding ink onto paper. After leaving a review, Emy contacted me and started working to resolve the issue. In the end, a replacement nib unit was sent to me in addition inside another order I had placed, works great. It was a bit of a pain in the neck to deal with but Emy was very professional and was looking to make things right.
That being said, I'm pretty happy with the Gravitas Quark. With it being a pocket pen, it's nice to carry with me at work for any writing/notes I have to take. Feels nice in the hand, threads in the cap as well as the threads on the end for posting take about one rotation.

Gravitas Quark - An excellent pen

This is my first pocket pen and I was quite skeptical if it would work for me. I have to admit that I was pleasantly surprised. The size of the posted Quark is close to the size of an unposted full size pen. Zirconium being a relatively heavy metal gives the pen a nice substantial feel despite the overall small dimensions. The grip section is really comfortable and the nib is excellent. The construction quality is superb.
Last but not least I would rate the buying experience from Pen Venture with A+++ and I definitely recommend them.

My wonderful first Titan pen

Beautiful colour. The nib is smooth and wet. The grip section is textured, I will not worry about writing with it in hot weather. This is my first demonstrator pen, I love watching the ink level drops (very slowly) in the barrel. The package is packed very securely. Thank you staffs at Pen Venture.

Gravitas - Vac 2.0 Aluminium | Black

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.

Gravitas - Vac 2.0 Aluminium | Black

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.

Platinum - #3776 Century Kaga Maki-e Sansui GT
Robert Moore
Platinum Sansui - Smooth Operator

I recently acquired the Platinum Maki-e Sansui pen in a Medium nib. The Pen Venture team was kind enough to carefully inspect and tune this pen before sending it on to me. Many thanks for that. It writes very smoothly and with a steady flow of ink. The Medium nib is my favorite nib configuration from the Platinum brand. The line width is nice and thin and always writes consistently right of the box. This lovely Maki-e pen was no different. I highly recommend it.

Gravitas #6 extra fine nib

The extra fine nib came tuned to perfection—a joy to write with. Thank you Emy!

Gravitas - Vac 2.0 Aluminium | Black
Jimmie
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!
