Description
Meet the Fifty4T Titan SL (Slim Line) - engineered to last, the Slim Line is a modern take on the fountain pen for those who find value in precision as much as personality. Every component is considered. Every material earns its place.

Titan SL derives from the Fifty4T Titan series, with smaller and slimmer proportions, equipped with a Steel #6 (Jowo generic #6 thread pace nib unit compatible). The cap and end knob are made in 6065-T6 aluminium for strength without excess weight - anodised with now a Flush-mounted clip via a precision dovetail joint, set at exactly 21°, the filing system is made from a combination of  304 stainless steel for long-term durability and Titanium chosen for wear resistance, now the TFS (Titan filing system) features a quad-ring (square oring with 2 contact points) made of PEEK HPV for exceptionally smooth mechanical operation, clear barrel is made in machined optical grade acrylic 

Available in Emerald Shadow, Bramble and Frozen Bronze, each finish offers a distinct character while preserving a refined, understated aesthetic.

At its heart is the Titan filling system, delivering an effortless, reliable full fill every time, with an impressive 4 ml ink capacity. The #6 stainless steel nib is available from Extra Fine to Broad, provides smooth, consistent ink flow for dependable daily writing.

This pen is packed with thoughtful Engineering & deliberate Material selection.

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.

A Fifty4T? Much closer to a 100 out of 100!

For the sake of proper disclosure: I have coveted a Conid Bulkfiller for a long time, since I first stumbled upon their ingenious (and back then - completely new and revolutionary) filling system. Alas, I hesitated long enough to realize that their current production & marketing model would yield nothing for me. Thus, I sought viable alternatives, found some - and wasn't satisfied with any of them. And then Fifty4T came along - and did it for me. I chose the SL simply because its bigger brother has no clip, and that's a deal breaker for me.
The pen is all I could wish for: I like its smooth, clean, high-tech design. The overall dimensions are just right for me (it is heavier than average, though, but not inconveniently so, for me at least). The EF steel nib (thank you again, Emy, for giving it your personal touch) is appropriately wet, and it's one of the smoothest in my collection - almost no feedback. Oh, and the filling system works flawlessly :)
As a bulk filler equivalent, it carries a huge amount of ink, and it is also a safety pen.
And last - but certainly not least - it is considerably cheaper than a Conid, without compromising functionality or quality.
Finally - a shout-out to the Pen Venture Team for their great service and excellent business.
Highly recommended all-round!

I am pleasantly surprised!

I didn’t do much research as usual, if I see Emy show it off on YouTube then it’s a purchase for me! It did not disappoint and it feels right up there with the best of the Gravitas…juicy flow, sturdy build, awesome material. I like it!! Thanks to Pen Venture for carrying this nice brand!

perfect choice, excellent service

The Fifty4T Titan SL is a perfect EDC pen: solidly constructed, excellent nib, a great writer and a practical filling system which is a joy to use.
Great service from Pen Venture and rapid delivery. I appreciated the handwritten note which added a touch of luxury and exclusivity to my order.

The filling system is just the beginning

I've always found Fifty4T pens rather pricey, but now I know you get all you pay for. The filling system is as efficient as advertised and the writing experience is top notch.

Funky and fun filling system

The fifty4t sl is a a smaller, but no means small pen from Fifty4t. Its about the size of a Pilot 823 ( just a tiny bit longer and wider). The grip section is made of stainless steel, but it's very grippy due to the textured finish. The writing experience is smooth and is a pleasure for long writing sessions. The filling mechanism is a fun change of pace. It's easy to use and packs a large ink capacity.

Gravitas - Quark Zirconium Stone Washed Pocket Pen | New |
Scott Y
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.

Gravitas - Vac 2.0 Aluminium | Black
Jonathan
The Vac 2

The Vac 2 is a refinement of both the Monster and the previous Gravitas vac fillers. This is a very robust, beautifully balanced writer that will bring pleasure to even the most particular purchaser. The filling system holds just the right quantity of ink. Long writing sessions are a breeze without the risk of having ink sit in the pen for extended periods. I have used this pen extensively since it arrived and have found it to be consistent and reliable. The nib is smooth and flows evenly with the lightest of touches. I prefer this pen over the monster because of its size and balance. The Vac 2 becomes an extension of my hand, allowing me to forget its presence and locus entirely, focusing on what I am writing.

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.)

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!
