Gravitas - Piston Carbon Black

This is one exceptional pen from the smooth cool touch of the Pultruded Carbon cap and body, to the easy uncapping/capping, and the ease in operating the piston when filling the pen. The large #8 sized nib was so well tuned, and smooth as to make writing effortless. This pen definitely does not disappoint.

This one is an absolute delight to hold and write with. The poltruded carbon fiber sure gives this a pen a special touch. Many thanks also to Emy who tuned this nib for me – it writes amazing. Anyways here are a few takeaways:
• Uncapping action is smooth (the cap is lined with Delrin) and takes about 1 ¾ turns.
• The cap is light and posts fairly deep and secure. Considering it is a pretty big pen to begin with I still prefer not to post it.
• The section has micro-grooves for increased grip security. They are much finer than other Gravitas pens that I have experienced.
• The nib is very stiff for a #8 size. I think Ben said this is also due to the black coating. I don’t mind at all.
• The piston moves perfectly smooth and the capacity is claimed at about 2,5 ml, which is pretty huge for a piston filler.

The carbon finish looks and feels fantastic in person, and I am extremely pleased with the pen. It arrived in exceptionally careful packaging, along with a thoughtful handwritten note. Emy and the Pen Venture team clearly took extra care with my order, which made the entire purchase feel very personal.

Esthetically pleasing, precision crafted, smooth writing FP. A joy to own. Pen Venture: great website, great service, fair prices, and a most trusted vendor.

The Gravitas Piston carbon black fountain pen has it all:

- The pultruded carbon looks gorgeous and gives the pen a substantial feel in your hand even though it's relatively light. This is not a cheap pen and it does not feel like a cheap pen. You're going to love writing with this one!

- I previously assumed that I might not like the big #8 nib but once you've started using this pen you're going to love the #8

- I have this pen equipped with an extra-fine nib, and combined with the black ebonite feed it is a generous writer that lays a nice and precise line on the paper

- That grip section: made from Titanium and with extremely fine micro grooves it does not even feel like metal and it doesn't feel slippery in the least! (I own three more Gravitas pens with metal sections, two Sentries and a Pocket Carbon: The section on the "Piston" is outstanding and my favorite.)

- And finally: the piston mechanism is extremely smooth and easy-going!

... Go and buy a Gravitas Piston as long as they're available!

Very nicely crafted pen. Writes very well. Time from order to delivery was excellent. Onlu issue is that the piston does not close snug with the pen and there is always a play which is a bit of disappointment. All in all very good pen.

Amazing fit and finish on a limited release pen. The pultruded carbon fiber offer an extremely unique textural feel. The #8 size PVD coated titanium nib is smooth and very wet for a fine nib. The piston filling system is very high quality held together with precise manufacturing tolerances. Everything about this pen screams "refined".

The purchasing experience with Emy at Pen Venture is very personal. He adds a touch of flair to each sale making you feel like you are a valued customer. Pen Venture and Gravitas have both earned my repeat business.

I recently received this pen, and all I can say is wow! The material is warm in the hand, while at the same time fits my hand perfectly! I was not only impressed with the quality of the pen, (as the fit and finishing and tolerances are better than if not comparable to the likes of Pilot/Namiki, Pelican, Mont Blanc, Lamy, or Visconti, etc.) but the pen's dimensions demonstrate a design language that reflects perfect balance and weight distribution, this is something that is rarely seen in fountain pen design.

The writing experience is sublime, with the No. #8 nib (mine is an EF) demonstrating exceptional consistent ink flow and the right amount of feedback under all writing conditions. It does not skip, stall, and does not dry out! The titanium section is perfect for my pen grip, and should easily accommodate most pen grips...

Finally, the piston fill system on this pen works flawlessly with the ink window accurately showing the ink level. All in all, I definitely recommend purchasing this pen if they are available. This pen is something that has to truly be experienced in order to understand how exceptional it truly is!!!

I love this pen in every way. I love customer service from Pen Venture. I wish this pen had a pocket clip. However, for normal daily writing I would go with this pen.

まず機能面は問題ありません。
ねじ式、ピストン吸入式、インク窓付き、キャップポストはもちろん可能。
キャップは2回転程で外れますが、実際の動作としては３～５回ひねることになります。
鉄ペンながら大ぶりのニブでしなやか、書き味はかなり滑らか寄りです。
重さに関しては35.7gと商品ページにもあるように、カーボンなので流石にほどほどに留まりますが、一般的なレジン製のペンなどよりはしっかり重量感があるので、軽すぎて満足できないということはありません。
重量の多くは軸の方にあるので、キャップポストしてリアヘビーということもなく、バランスも良いと思います。
私がこのペンの一番気に入っている部分は、やはりカーボン素材故の質感、肌触りです。
さらさらとした手触りは心地良いですし、キャップの天冠（は無いのですがそれに相当する部分）はまた少し手触りが違って、よりざらざら感が強めになっています。
この天冠部分の模様がお肉みたいで美味しそうだなと、見るたびに思います（笑）
書くことの機能を十分に果たしてくれることはもちろんですが、その上でペンを触る喜びを与えてくれる、そんな素晴らしいペンです。
私がお迎えしたのは178/500でした。

ちなみにカーボン軸といえば、ヴィスコンティのカーボンモアレも持っているのですが、あちらはレジンとの混ぜ物ということもあってか、もっと磨かれた手触りです。
それに対してこのグラヴィタスのカーボン軸は、それこそ木炭にも通じるようなカーボン感強めの手触りなので、同じカーボンでも個性があって面白いですね。

最後に、他のレビューにもある通り手書きのお手紙が添えられていたのは嬉しかったです。
達筆な英語だったので、普段筆記体を用いない私にはしっかりとは読めませんでしたが……（笑）

This was my first order from Pen Venture and I can't recommend them enough. This pen looks great and feels fantastic in hand. The #8 nib is a joy to use, the piston mechanism is buttery smooth. It is also one of the best writing pens I've ever tried out of the box. The fine nib has great flow and the line width is a true Western Fine. Thank you Emy for the perfect tuning, your service, and your handwritten letter in Lamy Petrol!

Also, thanks to Ben for these unique pen designs and flawless execution! I can't wait to see what Gravitas and Pen Venture have in store for the future.

Fantastic pen, looks even better in person than it does in pictures. The pen is made from high quality materials and has a real feel of quality about it.

The #8 nib looks incredible with the Gravitas logo and is tuned to perfection by Emy. It definitely writes on the finer side of medium, but this is not a problem at all.

This was my first order from Pen Venture and it even came with a handwritten note which adds a real touch of class and shows that this is a retailer who goes above and beyond. I cannot wait to order from them again!

Looks good, feels good, and writes well. Nicely tuned, Smooth cap operation without excessive turns. Would like option for a roll stop. Excellent pen and great service from Pen Venture.

Gravitas - Piston Carbon Black

I am amazed with the quality of the pen, the material is mesmerizing, the #8 nib is fantastic and it arrived super fast.

Put a clip on it! Too light otherwise. Likes to run away when put down.

An excellent addition to the Gravitas range. Well made using premium and unique materials, the carbon body has a wonderful feel to it and the #8 sized black nib looks impressive and writes smoothly out of the box, maybe with the extra help from Emy's checking/tuning. Excellent service and attention from Pen Venture!
This one gets to stay for use at home whilst its sibling, the Gravitas Pocket Pultruded Carbon Fiber, get to go out with me. Love them both along with the many other Gravitas pens I have purchased through Pen Venture!

The pen is as close to perfect as any pen can be. It weighs just right in the hand and the carbon fiber material is a delight to the touch, smooth with no visible voids (which carbon fiber is prone to). Not to mention the impressive #8 nib. I did not specifically request the nib to be tuned, but Emy went out of his way to tune up the nib before shipping. This is very much appreciated!

This is my first ever order with Pen Venture. The ordering process was painless, and shipping notification was received in less than an hour of order confirmation. It arrived well packaged and compact which I really appreciate. A handwritten note from Emy added a level of personal care that many other vendors could learn from.

Thank you to Emy and the Pen Venture team for such a pleasant and quick turnaround. I will definitely come back for another purchase in the future!

I recently purchased the Gravitas Piston Carbon Black fountain pen from Gravitas Pens, through Pen Venture, and I couldn't be more satisfied with my decision. This pen marks the very first piston filler model from Gravitas, and they've absolutely nailed it. The piston mechanism operates flawlessly, rivaling the smoothness and precision typically associated with industry giants like Pelikan and Montblanc.
Constructed from outstanding quality materials, the pen features a unique, pultruded carbon fiber body, which offers an exceptional tactile experience comparable to the iconic lava-based Visconti Homo Sapiens pens. Its craftsmanship and attention to detail truly set it apart.
One of the most impressive features is the sizable nib - slightly larger than that of the Pelikan M1000 - which, despite being steel rather than 18k gold, delivers an incredibly smooth and juicy writing experience. I suspect the meticulous tuning done by Emy at Pen Venture played a significant role in this exceptional performance.
I was particularly delighted by the thoughtful touches from Pen Venture: the handwritten note from Emy added a personal warmth to the robustly packaged box, alongside generous extras such as a notebook, a bottle of ink, and a pouch featuring the Gravitas Pens logo.
Being the proud owner of pen number 119 of a limited edition run of only 500, I feel genuinely privileged. Both Pen Venture and Gravitas Pens deserve top marks for creating such a superb writing instrument and providing impeccable customer service. Highly recommended!

What a pen! When I opened the box I wanted to put it on display, but I resisted & took it out of the box to feel it in the hand - wonderful! I wanted to keep it pristine but loaded it up with Taccia Ainezu, a lovely ink that complements the pen itself. Emy had personally tuned the nib & it immediately started writing, very smooth, no skipping, & no start up problems! A great addition to my collection!

I enjoy the way that the Gravitas Carbon Piston Fill fountain pen feels in the hand. It has the weight of a Pelikan M800, but it does not create any type of hand fatigue. The fine nib has a smooth flow to it, and the ebonite feed gives it a wonderful flow. I wish that it had a clip or roll stop to it because I don't want it to fall off a table or any inclined surface. I really appreciate how Emy sent me a complimentary bottle of KWX ink with my purchase.

A highly anticipated and very well-writing pen. The protruded carbon fiber cap and barrel are slightly irregular feeling but seem very solid and quite unlike acrylic or titanium. They have a very nice "feel" to them. The cap is lined with something - ?Delrin. It screws and unscrews very smoothly. The piston works very smoothly too. A high quality product that is worth the somewhat high cost of the pen.

This is not the first Gravitas Pen that I own. It has the dimensions that I like, similar to the Sentry. The nib writes smoothly with no hard starts or skips. The material feels and looks wonderful. The ink window under the cap is a nice touch to make sure that you have enough ink to put the pen in your briefcase. I really enjoy the attention to detail that Gravitas puts into their pens.
