Fifty4T - Titan Slim Line Aluminium Frozen Bronze

The build quality and machining tolerances of the pen itself are flawless. The mechanism is unique with far more pros than cons, and from an engineering standpoint, it is truly stellar.
However, as the title suggests, the nib is a bit underwhelming—it's just a standard JoWo #6 nib lacking any real character. Then again, I tend to prefer a feedback-heavy writing experience over buttery smoothness, which might be influencing my take. The balance, engineering, and finish are spotless, and even the nib issue is easily resolved by swapping it out for a custom one. I ended up spending an extra $50 for a custom nib, but it ultimately resulted in a flawless pen.

Very interesting pen, well balanced and with a clip that helps to carry in the jacket pocket. Excellent article

I wanted to drop a quick note to say that the Titan Slim Line is a very impressive pen and wonderful to write with! I started with a medium nib, which I quickly realized wasn’t what I really wanted as this pen felt like a daily writer, so I replaced the nib with a standard Jowo fine that perfectly screwed right in. The fit and finish are extremely nice on the pen! It really feels like one solid piece since the clearances between both the screw down finial and the metal to acrylic sections of the body are so finely machined! I really love the micro grooves in the section that give it a very pleasant feel when writing. The exceptionally smooth filling mechanism and the amount of suction produced is class leading in my opinion. Some will feel the price is too high due to no gold nib, but I’ll say the pen puts gold nibbed pens with basic acrylic bodies and converters in second place to me. Finally, Pen Venture had the pen to my house in the US in less than a week, including of course, a lovely hand written note. I suggest buying this pen if you are on the fence and seriously considering it if you are looking for a unique and beautiful new pen.

This pen is beautifully crafted and has a remarkable filling system that is a joy to use and holds a remarkable 4.0ml of ink. The nib writes very smoothly but…skips a bit and even occasionally railroads. I’ve cleaned the pen thoroughly, tried different inks, and even tried a wetting agent (White Lightning). These have helped some, but not eliminated the problem. I honestly am a bit disappointed. Perhaps PV will get back to me with a solution.

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!
