My new Carene arrived three days ago. This fountain pen writes beautifully. It is smooth and comfortable in the hand and looks very elegant. The quality of the manufacture is superb. The nib is very smooth and solid to write with.
Emy’s care and attention was greatly appreciated. He went to great lengths to ensure I was provided with exactly what I ordered. Delivery to the far side of the world was quick, efficient and secure.
I recommend both the fountain pen and Pen Venture to any prospective purchaser.

Pen shipped fast! Even included a hand written letter from Emi and both,EF and F, were a dream to write with!

Perfectly tuned nib, ultra-precise assembly that ooze of quality and comfortable to write with. This pen redefined what a grail pen is for me. I didn't buy it as a grail pen, I have way more expensive pens in my collection, many with gold nib yet when I pick this one it feels really special, every time.
I'll never see steel nib the same way after this pen, Gravitas shown that a steel nib can be as good as any gold nib.
Thank you Gravitas and Pen-Venture this pen is special !

Dear Pen Venture,

Dear Emy,

I would like to thank you personally for the professional and quick service I have received from your company. I am the proud owner of at least 16 pens purchased with you and all, everyone of those purchase experiences have been excellent. I want to also thank you for joining up with Gravitas Pens and having them be available thru your company. All I can say is that I am a very happy customer and plan on continuing to be one.

Best,

This is a wonderfully engineered fountain pen. Great design, excellent filling mechanism and well balanced for its size The ink capacity is incredible and the medium nib is a joy to use. I filled the pen with Birmingham Eucalyptus Stem, and the dark green color looks great through the substantial ink window.
Great value and highly recommend!

I had my doubts about the classic "Black & Gold" color scheme, but this pen's design hits different once you actually hold it, and especially once you write with it.
Due to its construction, the Carene is slightly heavier than one would expect for such a slender-looking piece, but it's that heft that gives it a reassuring, premium presence in-hand. And the black lacquer finish makes the pen body feel smooth in a pampering, luxurious way.
The nib is a true masterpiece, in looks and in actual use. The Medium variant lies firmly within the Western / European range of the size, the ink flow (using Waterman Serenity Blue ink) is generous without being excessive, and the writing feel is buttery smooth. Tested on a Rhodia DotPad notepad, the Carene glides effortlessly while laying ink down evenly and consistently.
Writing with the nib held upside-down, while possible (and resulting in thinner lines), isn't something I'd recommend for long stretches of words, as the tipping is left sharper on the top end, translating into a distractingly scratchy experience.
Also, while the 18K nib does have some measure of bounce, it's far from a flex-nib, so calligraphy enthusiasts looking for line thickness variation higher than 2:1 won't find it here.
Overall this Waterman Carene fountain pen, while not as head-turning looks-wise in the Black Sea GT finish (compared to other editions of the same model), still manages to amaze with its in-hand feel, enabling an exquisite writing experience that few other pens can match, and is in my opinion a worthwhile purchase for writing, jotting and journaling addicts looking for the next level of writing pleasure.

I ordered a Lamy nib for my old Lamy Safari, which had a broken nib. Originally, it came with a fine nib, and most of the fountain pens in my collection are fine nibs as well, but I decided to try a Lamy medium nib this time. The nib writes perfectly!

It was my first order from Pen-Venture, and I’m really impressed with the service. It was dispatched the same day I placed the order. The handwritten note from Emy was also a lovely touch.

Thank you!

Ordering and testing the carbon pultruded pocket fountain pen from Gravitas I wondered about the haptic experience of the material. And I am absolute amazed with the warm and smooth experience of holding and writing. Also the nib works perfect. The look gets positvereaction from clients.
Also have I to mention the perfect service and the personal letter from Emy.
Great experience, looking forward for further purchases.

I’d been waiting for this Monster for what felt like at least a year or close. The first day it was available I bought one, but the decision was tough between the silver and the black. I went with the silver.

After getting the silver in broad just four days later, I was so impressed with the nib that I went out of my comfort zone and bought a fine nib unit. It arrived 4 days later and is the best fine nib I have ever written with.

As more and more folks got their Monsters I kept seeing the black and didn’t want to miss out so I had to have it too! I bought the black with a medium nib so now I have fine, medium, and broad. I’m not disappointed at all!

the gravitas sentry - polycarbonate has quickly become one of my favorite pens. the nib is so smooth and writes like a dream. i love being able to view the ink i have loaded through the frosted exterior finish. love, love, love. 🩷🩷🩷

クラーケンフィラーと名づけられたこの機構が心をくすぐります。
インク窓とかいう半端な機能ではなく、インクタンクまるまるスケルトン仕様にすることによって、どれくらいのインクが入っているのか丸わかりで、どのように吸入しているのかを堪能することができます。
基本は負圧によって吸い上げるシステムで、これ自体は目新しくはありませんが、インクを入れずに動かしてみるとわかるように弁が2パーツに分かれていて、インクが無くなってきたと思ったら弁を少し動かすことでインクタンクから手軽に補充できるようになっています。
ボタ落ち防止の機構とだけ見るとこれもよくある機能かもしれませんが、これだけのバカでかインクタンクということも相まってロマンを実現した感も強く、何だか吸入しているだけでも楽しくなってしまいます。

吸入機構以外に関しては、安定したグラビタス品質だなという感じです。
スチールニブながら#8サイズの大きなニブは満足感があり、書き味も滑らかで文句なし。
グリップ部（首軸）が滑り止めのためか、細かいストライプ状の凹凸があるのは好みが分かれるところかもしれません（私は嫌いとまでは言いませんが……といった感じ）。
キャップポストは一応出来ますが、意識した造りというわけではなさそうなので、すわりはよくありません。振り回しすぎないようにしましょう。
あとクリップは無く簡単に転がりますので、お気を付けください。

まとめとして、このクラーケンフィラーの為だけでも買う価値はあったなと思いました。
万年筆ユーザーがインク切れをそんなに心配しているか？と言われると、むしろインクが切れたらまた吸入できると喜んでいそうな気もしますが、それはそれとして、ロマンあるバカでかインクタンクは良いものです。
あなたもこの大量吸入で気持ちよくなりましょう。

I recently purchased the GRAVITAS – ULTEMATE VAC ACRYLIC from Pen Venture, and I couldn’t be happier. This is both my first Gravitas pen and my first order from Pen Venture.

Delivery was incredibly fast—I placed my order on August 12 (evening, USA time) and the pen was in my hands by August 18 via DHL. That speed alone was impressive!

I reached out to Emy to ask about setup, and not only did he set up the nib, but he also prepped the pen and included a handwritten note thanking me for my purchase. That kind of personal touch and customer service is rare these days, and it really stood out.

As for the pen itself: I’ve been eyeing this model for a while, and when I saw it on sale, I finally decided to pull the trigger. I’m so glad I did. The ULTEMATE VAC ACRYLIC is everything I hoped for and more. I love vac-fill pens (my Pilot 823 is another favorite), and this Gravitas instantly joined that league. Even without a gold nib, it writes beautifully—smooth, consistent, and very enjoyable. The weight and balance in the hand feel fantastic, making it a true pleasure to write with.

After just one day of use, I can already say this has become one of my favorite pens. And one thing is certain: this will not be my last purchase from Pen Venture.

Thank you for everything, Emy!

The pen is really large, as well as the nib. Filling mechanism works very well.
Surprisingly I'm still consuming my first fill ;-)

Great customer service as always!

I wanted to try out that highly praised Tomoe River paper for quite some time now and yes, it is nice writing on it.

I was looking for an ink that matches to the pen I intended to buy. It was a little difficult to decide via photos displayed on screen, but in the end ink and pen match quite well.
The ink writes well and looks quite nice. Another benefit is the relative low cost which makes it easier to fill several ml at once into the pen.
