Description

Introducing the Quark, a pocket fountain pen that redefines compact convenience without compromising on performance. The section is made from anodised aluminum with micro machined grooves and the cap & body are made in 6061-T651 aluminium anodised with a bead blasting finish. Shamrock Green and Orange is part of the new 2025 line up of Quark colors and brings with it a refreshed look with a matching color section and an upgrade to ACME threads for capping and posting.

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 ACME 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 grade 5 material with micro-machined grooves and a bead-blasted finish.

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

This pen is not recommended to be used as eye-dropper and it can be inked and used with standard international ink cartridges.

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

Gravitas Quark Shamrock Green Pocket Pen

I bought the Gravitas Quark Shamrock Green Pocket Pen and some other pens during Black Friday from the Pen Venture online shop, and I must say it was an outstanding experience. The prices and selection were extremely attractive - honestly, one of the best Black Friday deals I can remember. The pen itself is small but performs excellently. The nib came well adjusted and writes smoothly and generously, making it a real pleasure to use. The pen is very light and compact, which makes it ideal for carrying and traveling, especially when weight and space matter. I’ve only been using it for about a week, but so far the coating appears to be durable and scratch-resistant. I’m very happy with this purchase and truly appreciate the quality of both the pen and the service. I wish the Pen Venture team great success and thank them for a wonderful surprise and excellent products.

Beautiful tiny metal nib with a huge nib

It's not my smallest pen, but definitely the smallest one with a big nib!

Fastest customer service I have ever experienced. Will be buying again at Pen Venture. Loaded my green Gravitas Quark up with Mont Blanc Irish Green and it writes beautifully as I knew it would.

Really beautiful color! Perfect size in the pocket and in the hand, and I love how it still packs a #6 nib!

Sailor - Pigment Ink Souboku Blue-Black | Permanent | 50ml

Alan Hamilton

Love this ink!

It is a beuatiful color and seems to work well in the pens I have tried out. No issues, and it has the waterproof qualities I was looking for.

Diamine - Desert Rose | Exclusive Pen Venture | - Bottled Ink 80 ml

Garo

Desert Rose is a beautiful, elegant ink with a soft dusty rose color that stands out from the typical reds and purples. I currently have it inked in my Laban, and it’s a perfect match. The ink has excellent flow, looks sophisticated on the page, and gives the pen a unique personality. It’s a color that always catches my eye when I flip through my notebook.

Diamine - Neptune Blue | Exclusive Pen Venture | - Bottled Ink 80 ml

Garo

A beautiful saturated blue that strikes a great balance between professional and vibrant. It has excellent flow, good lubrication, and behaves well on quality paper. If you enjoy rich blue inks without venturing into teal territory, this is a fantastic exclusive.

Gravitas - Vac 2.0 Filing System Tool

Garo

Simple but worth having. It makes maintenance much easier and fits the Vac 2.0 perfectly. It’s one of those accessories you may not use often, but when you need to disassemble the pen for cleaning or servicing you’ll be glad you have it.

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.
