My pocket pen quest has led up to a Gravitas journey, starting with the OG pocket pen, winding 'down' (size-wise) along the Dinkey and landing on the Quark.
I am fond of all of them, even though some have come with growing pains, which I now consider to be expected in a designing process. Variation is the colour of life, broadening the frame of reference, making me appreciate every piece of that puzzle, including their nooks and crannies. Musings aside, I enjoy ultem for its silky touch, practical transparency and featherweight in a mini Quark as well as the heft and gravitas of copper or more playful to slightly ostentatious colour scheme in the full size OG... and every permutation in between. They all have their place for & in this pocket pen fan & éventail, respectively.

Out of all the pocket pens I carry, this one has hit a sweet spot. It is ultra light & ultra durable (even though the former seems to contradict the latter), is still manageable for a quick note when uncapped and writes very comfortably when capped. Despite the fine line, it has a generous flow, never once failing to put down a glorious amount of ink (thanks for tuning, Emy). The transparent nature of ultem makes checking the ink level through the barrel a breeze and provides a nice feedback on the pen's barometer via the cap. It fits securely in my EDC, its dimensions blending in perfectly.

I have less and less pocket pens in rotation: my Liliputs are being retired (their slightly but significantly smaller diameter leading to cramping up) and I tend to be overly protective of some more classy/vintage Japanese models (which is contradictory to a fountain pen primarily being an instrument), but the Quark has put itself confidently on that balance point between being a practical & reliable tool on the one hand and 'a thing of joy' on the other, making the task of jotting down, scribbling, noodling or sketching a game rather than a chore.
- Homo ludens

This is an update/addendum after the "cap mishap', specifically to thank Emy for being so helpful, kind and efficient. The speed and adequacy of having the pen picked up, fixed and sent back across borders made it feel like he was just around the corner. If that were truly the case, I would have dropped by and bought him a coffee or whisky a long time ago.
Emy's service is in a class of its own.

A very beautiful ballpoint arrived very quickly.
Thanks so much!

...and that is the only thing I regret about my purchase. Seriously... Ireland, Romania, then off to pokey old Fort Wayne Indiana? Ridiculous. Rueben had the nib tuned up and working brilliantly, and his team had it shipped (with a lovely hand written note) quicker than I expected. The Sentry (my second) is perfectly balanced in your hand, has a great grip, and writes wonderfully. Ben is an amazing craftsman. Buy your next Gravitas from Pen Venture!

So everything that I can knit pick with the pocket pen, was addressed here. Nib too small, this pen is a big juicy nib with positive feedback a bit too heavy, but then again it’s solid brass I’d sure hope it wasn’t light. Literally nothing to whine about, okay I have one slight kink to work out, for me I’d rather a custom nib option, as opposed to the standard F, M, and so on. But this is such a minor issue just me coming up with something I really do think this is close to perfection

The pen is exactly what I hoped for. I love titanium as a pen material, and this hits the nail on the head for me. The two potential negatives I could provide for prospective purchasers are: The coating will develop the usual ring where the cap posts, as is usual for most metal versions of this pen, which is something you should consider if you are bothered by signs of use. Additionally, the coating is a fingerprint magnet, although that is remedied easily enough with a quick wipe down. However, the overall package is great: a nice size nib, comfortable weight, generous diameter and length when posted, a handy roll-stop, quality manufacturing in finish and threads, etc. The coating has a beautiful purple-blue gradient that I find quite appealing in comparison to bare metal; the outside can be a bit slick, but the section is textured which provides a totally acceptable grip. I chose the fine flex nib, which writes well without pressure, and adds a bit of line variation with pressure. It won't compare to a wet noodle, but is enough to keep the writing experience varied and interesting.

This is my second time ordering from Pen Venture, and both have been painless. Shipping was fast, the nib arrived well tuned both times, and both included a nice little note. The note is a good example of something that's not necessary but really improves the experience, and I'm glad they do it.

I love everything about this pen! I can honestly say that the customer service I received from Emy made the experience so much better! He took the time to carefully tune the nib before sending it to me with a handwritten note and even added a personal detail to my pen that I greatly appreciated. The pen writes incredibly smooth and wet. Shipping was quick and the pen was well packaged. Overall, one of the best pen and customer services I've ever had.

This pen, the Ondona, writes smooth. It has a nice thickness, and thus feels solid in my hand when writing. Also, having 1.5ml of ink is like an almost never ending supply. The shade of blue makes the guilloche waves beautifully discreet. The steel with the gold trim looks very nice! Leonardo

Emy really calmed my fears when I asked him about the Ondona. A pen I had from another distributor kept leaking, despite their "finding nothing wrong with it." Two white shirts could testify in my favor. Anyway, Emy sent a note explaining all he did to test the pen and make sure it would operate perfectly. Thank you, Emy!

The pen is beautiful and the material feels soft to the touch and very pleasant to hold. I got a B nib and I love how it writes, very smooth and juicy. The customer service was excellent and I'm very happy with my new pen.

The pen in wonderful to use. This is for sure my edc pen of choice.

My confidence to purchase the Gravitas pen was greatly enhanced when I saw that Emy and Pen Venture is involved. Thank you Emy for the quick delivery, and also for testing the nibs as requested. Much appreciated !

So happy with my order and the shipping time was fast, even to the US!

Been a medium and fine nib person. Wanted to try a broad nib and Lamy's easy to change nibs and affordability are a combo hard to pass on if you want to try new styles. Would be cool if with this system Lamy had other grinds or speciality nibs, that's the only downside I see.

I was very impressed with the pen when I got it. It has a beautiful guilloche design and a lovely blue color with rose gold details and nib. The nib is very smooth and was checked and tuned by Emy who did a great job.

I recently purchased a new Gravitas Pocket Pen from Pen Venture. The transaction was easy and secure and the shipping followed without delay. I am delighted with the pen, especially for its excellent writing out of the box. I especially appreciate the kind personal letter of thanks from Emy. What a pleasant experience.

I look forward to returning for another pen and other accessories very soon.
