If you haven't pulled the trigger on one of these yet — do so. Mine arrived quickly with a hand written letter (Not a note — a letter) telling me it was tested and tuned, and Emy did not disappoint. For me it has the perfect amount of feedback from the nib. Not too scratchy or too slippery. With a medium nib it's nice and juice on every kind of paper I've tried it on — even Tomoe River which my fine nibbed Sentries have trouble with.

I went back and forth on whether to get this or not. Ultimately, this was one of those purchases that has brought me joy every time I use it.

Stunning! Super fast shipping! Delivered in leas than a week!! Wonderful perosnal note and the nib was fine tuned by Emily! Steller experience!!

Great pen with a finely tuned nib with a a great ink flow that keeps up one of my top pen in my 60 plus fountain pen collection also reall quality build and materials purchsed at pen venture! One tiny little detail is that you may want to check Titanium theeads for some small burs that can overtime do some damage, but it is easily removed with some fine sand paper i used 1200 grit dura gold.

smooth like a glass. Writes very well and to be honest the steel nib givez me confidence to not worry about presure too much :) this pen is for my taste beautyful and performs like a dream. If you would ask me what is my Grail pen this one would be one of those on the top. there is also Carbon fibre version and I have to tell that that one is even better because of the raw CF feel and texture

The Ultemate Vac is a wonderful pen with a very precise writing feel. The build quality is excellent and the pen is so pleasing to hold. All around, this pen is a joy!

Many thanks to Emy and Ben for the great experience.

Fukaki is a nice blue.
Koiai is a darker blue.
The two blues are reminiscent of Hokusai's The Great Wave.
Benitsuchi is a red brown.
Sabimidori is a dark green with fairly strong red sheen on Tomoe River paper.
No sheen on Clairefontaine.

Scribo Verde Mediterraneo is a beautiful ink.
It has a nice little shading and little red sheen on Tomoe River paper.
Only little shading on Clairefontaine paper.
Not waterproof.
The color of this ink is reminiscent of the color of tropical seas near the coast.

A beautiful, eye-catching pen that writes so well.
Excellent service from Pen Venture.

Awesome pen. Great pen body. Threads on the cap aren't perfect but almost perfect. The balance of the pen in the hand is very good. Very comfortable pen. The fine nib was really well tuned. One of my best nibs, better than most gold nibs I own.

The Gravitas Ultemate pen is a superb piece of engineering and an absolute pleasure to write with. Pen Venture are a joy to deal with and Emy’s personal attention to ensuring that the nib is to the purchaser’s specification was greatly appreciated.

The nib and feed on this pen are amazing. I don't know what magic Emy performed, but it's perfect. I also own a Gravitas Piston Carbon Black (I think I have a thing for pultruded carbon fiber now), but I think this Pocket nib/feed combo is even better than the #8/ebonite feed found on its bigger brother. If all Gravitas pens came with this feed, I would buy them all...

My only qualm with the eyedroppered Pocket is not being able to tell how much ink is left (it'll be quite messy to check periodically).

Pen Venture was great to deal with.. Very professional and helpful with regard to chosing the nib that would fit my style. Shipping was efficient with communication via email at various shipping status points. The a personal note from Emy added such a extra class of excellence and service. The Fifty4t is an excellent pen. Love the modern pen. Very different to my Montblanc, Visconti, Sailor, and Pelikan pens. Great add to the collection. Quality of pen is excellent and writing very smooth. Stainless Nib is as good as more expensive gold nibs in my opinion. Inked with Sailor Four Seasons Rikuacha [****] Ink. Highly recommended the Pen and Pen Venture. I also bought the Gravitas Ultemate Vac. Will purchase again from Emy and his team.

Very sturdy.
Well tuned broad nib.
Confortable in the hand.
Need to be capped carefully.
A lilttle backweighted but in a good way : the section is ultem, not metal.
Amazing design.
I love it.

After much anticipation, this Fifty4T Full Titan clear acrylic demonstrator pen arrived today, amazingly fast for overseas shipping. Of all my pens, this one is unique for its "industrial" look, quality of materials and machining, brilliant filling and sealing mechanism and huge ink capacity. Love the large #8 nib size (with medium tip), though I was concerned about it being stainless, my first ever. Surprisingly, it virtually floats over the paper with no pressure required, laying down an even flow of ink (Robert Oster "Motor Oil"), though without the line variation I prefer. (Most of my nibs are either fine flex or medium Cursive Italic.) Perhaps other nibs will be available in the future; don't know if stainless can be custom reground. My only other wish is that it had a clip; pocket carry will require it to be in a single pen case to prevent it from sliding out. All things considered, I love this pen. It feels good in the hand and just keeps writing and writing. By the way, the personalized letter of appreciation for my purchase from Pen Venture was a touch of class. They seem like nice people, offering help if needed and welcoming comments.

I am so blown away by the quality of these pens. I was a little skeptical at first. The moment you hold this pen in your hands, you will know you have a high quality, well crafted and beautifully engineered pen. It feels beautifully made, and done by hand. As if you were making it for yourself. Highest quality and highest standards.

I really commend Emmy for the wonderful experience which is also a big part of buying a quality pen as well. It felt as if I were personally buying this pen straight from Emmy himself. Thank you Emmy for personally Tuning the nib, it writes beautifully! The Handwritten Letter was a such a wonderful surprise to find! I can’t recommend them. I will be a loyal customer to pen venture from now on because of the amazing experience from start to finish. I couldn’t be more happy that I chose to go with Pen Venture and Gravitas. I love what they stand for and the passion that they have for fountain pens. You will not be disappointed!
