Description

The Pocket GT is a refined take on the classic pocket pen, crafted for those who appreciate meticulous design and functionality. At its core is the standout s136h steel clip, engineered with precision using wire EDM from stainless steel, heat-treated for durability, and crafted to fit seamlessly at a precise 21-degree angle into the cap. The polished, brushed finish highlights its unique dovetail integration, creating a sleek profile and robust functionality. The cap, body and the section are machined from raw Brass with an even texture and treated with a patina finish - Shipwreck. This finish will further age and develop accordingly to each user and its pen and each pen is displaying a unique pattern and look.

The cap is sculpted with three facets: one to stabilize the pen on flat surfaces and two that elegantly frame the clip, accentuating its minimalist style. The body is fitted with Quad start threads, offering the flexibility to position the clip just as you like. The posting is done securely with threads and the clip is always aligned with the nib when the posting procedure starts from the aligned point. Each Fifty4T Pocket GT pen is equipped with a screw in size 6 steel nib unit, available in the following sizes : Extra Fine, Fine and Medium - powered by a ABS plastic feeder. Fifty4T Pocket GT is threaded to fit* standard JOWO size 6 steel nib units. (*please check for fitment before committing to close the cap - not all JOWO size 6 steel nib units are standard - we are not liable for any damages that may occur in the nib swapping process - proceed at your own risk).

The Pocket GT model is designed to operate with Standard International Cartridges (small) and it can fit some of the smaller generic converters on the market. The pen doesn't come with a provided converter from the manufacturer. 

Fifty4T is a new brand originating from Ireland that is focused on offering fresh look, deeply rooted in Bauhaus and minimalistic style - choosing to use in its line up high end materials and a keen eye for machining.

Love this pen!! Very cool

Love the look and feel of this pen. I was able to switch out the nib for an extra fine and it is a very smooth precise writer. Will carry this everywhere. Emy was great to work with. Just hated the added costs to ship/sell to the US. Not a fault of Pen Ventures. Really like the look and feel of Fifty4T pens.

A Worthy Sequel to an Awesome Pen

On its own, this pen feels very durable and premium, and the bead-blasted, matte black coated treatment gives it a very “professional” vibe. The Fine nib is bouncy and smooth, very usable on the underside as well (with added feedback, but not scratchy), the ribbed steel grip is very comfortable, the feed holds a lot of ink on its own, and the reservoirs behind it will keep it in writing condition for dozens upon dozens of pages after a fill.

The cap screws open and closed smoothly, with a very satisfying click at the end when closed; it posts deeply, and it also posts securely after being pressed down slightly on the barrel. It is light enough that it does not back-weight the pen significantly when posted.

The barrel construction, along with the newly-implemented Kraken filling system, ensure a significant amount of ink is pulled in from the first try. Much like the main cap, the blind-cap screws open and closed smoothly for refills or ink transfers between reservoirs.

Compared to its predecessor:
Fewer transparent areas overall, but the Vac 2.0’s structure feels more solid than the Ultemate Vac.
The body thickness and thread profiles are different on the Vac 2.0 than on the Ultemate Vac, no mix-and-match potential here.
The matte black coating gives the pen a more refined, premium feel on the metallic parts.
The inner lining of the cap doesn’t get stuck in the barrel thread as often, and when it does, it either slips back into correct position, or it is easier to unscrew and reposition, without the metal thread eating into the cap material.
The coated, no-breather-hole design of the new Gravitas steel nib may not be to everyone’s taste, but I like it a lot, and functionally, this nib feels more bouncy and polished, with smoother writing than its predecessor.
The feed seems to pick up a lot more ink on its own from just a 5-second dip, and the small reservoir behind it looks to have more capacity to back it up before needing to unscrew the blind cap and refill it from the large reservoir.
The Kraken filling system seems to suck up significantly more ink per pump than the mechanism from the Ultemate Vac.

Overall, a very well made fountain pen, and a thorough refinement to an already excellent design. Very satisfied with this purchase!

Gravitas - Vac 2.0 Aluminium | Black
Andreas Andersson
Substantial, reliable, and smooth

The Gravitas Vac 2.0 is an amazing tool for handwriting. The nib is smooth, distinct, and reliable, and it has some weight due to its durable materials, black aluminium/aluminum and ultem, the perfect combination of a tool which will survive most of us, still functioning if the internal vacuum piston system is cared for. I have enjoyed this fountain pen for seven days and I am pleased to say it is one of my better ones, and it is fun to use. I recommend it.

(Emy was correct: The nib has great flow, about six drops of ink will automatically flow from the nib after I have just filled it, after that no problems; tissue paper or the ink bottle under the nib until that happens is recommended, other than that: an excellent fountain pen.)

FANTASTIC !!!!!

What a fantastic pen—and customized too!

It writes beautifully and arrived surprisingly quickly, even though I’m in Canada. This is my third order from Pen Venture, and once again, the experience has been outstanding. It's always a pleasure to come back.

My Gravitas arrived perfectly tuned and was ready to write straight out of the box. I filled it with Pelikan Royal Blue, and from the very first stroke, it was smooth, consistent, and an absolute joy to use.

I own several excellent fountain pens, including a Pilot Custom 823, a Sailor 1911, and a Leonardo Momento Zero, and I can honestly say that this Gravitas holds its own among them. It is remarkably well made and comes very close to being the perfect writing instrument.

A big thank you to the entire Pen Venture team for the exceptional service, careful tuning, and attention to detail. I’m already looking forward to my next order!

Great Little Monster

Wow!
Just like the Monster but thinner. For me it is more comfortable for longer writing sessions. The filling system is stellar. Holds lots of ink. As always Ben Walsh and Emy have delivered a innovative and enjoyable writing experience. Can't wait to see what's next. Keep up the wonderful work!
