Description

The new Gravitas Pocket Raw Copper is an ultra-portable fountain pen built for life on the move. Now in its upgraded version featuring Delrin sleeves (soft posting / improved cap seal) and ACME threads, this version along with Raw Brass skip the passivated coating, allowing a rich patina to form over time—each pen becoming uniquely yours. For a shiny look you can use a jewellers cloth to bring back the fresh copper.

Its triple-start cap opens in just 1.5 turns and features a flat side that works as a roll stop. Post the cap, and the Pocket transforms into a full-size writing instrument. A stainless steel 304 section with micro-machined grooves offers a secure, comfortable grip while keeping the weight balanced.

Equipped with a size 6 steel nib (compatible* with Jowo No. 6 generic steel nib units) available in : Extra Fine, Fine, Medium and Broad, each Pocket comes with a standard cartridge converter. Tough, compact, and endlessly personal, this is a pen that evolves with you.

*when swapping for a different nib unit you are sole responsible for checking the fitment of the new nib - we are not responsible for fitment or any damages that may occur from the instalment/use of non gravitas nibs/nib units.

Note: Brass and Copper naturally develop wear marks and color changes with regular use. In the process of packing we handle these writing instruments which may arrive on your side with more or less visible patina - this is a natural process which doesn't consist in a call on warranty or replacement

Great Pocket Pen

This is a pocket pen you can carry in your pants pocket. There is no clip, so you can’t clip it to your shirt pocket (with or without pocket protector). It’s kinda heavy, so you want to make sure it doesn’t fall out of whatever you carry it in. And finally, its outer shell is made from solid copper, a relatively soft metal that’s not particularly scratch, impact, or corrosion resistant. The copper will discolor quickly from humidity, as well as moisture and other chemicals your fingers have on them when you touch the pen. Your fingers will rub off some of the darker oxidized copper, leaving brighter shinier spots wherever your fingers habitually touch the pen. And let’s not forget about the oligodynamic effect that compounds and amalgams containing copper have on microbes! Not quite as effective as vaccines, but close.
In addition to the darkened and spotted appearance, my pen has also accumulated some scratches from posting the cap. I can’t write with the pen without posting the cap on the back of the barrel, because it’s a pocket pen, designed to be short enough to fit a pants pocket. I accept the scratches and spots as “comes with the territory”, just like having room for only one standard international cartridge, or the supplied mini-converter.
And here’s where I found an unexpected shortcoming: ink flow, specifically the lack thereof. I’ve used several of my nearly 100 different colors and brands of ink in the mini-converter. Almost all of them started to cause ink starvation sooner or later. I was able to replicate this phenomenon by using the mini-converter in one of my Sentry pens, where I also saw ink starvation. Similarly, ink cartridges cause ink starvation. With the mini-converter, you can at least “push” more ink into the nib unit to continue writing, but squeezing the cartridge may cause the cartridge to split, which allows air to get in through the crack, which causes flooding of the nib…
Surprisingly, Pelikan 4001 Königsblau has provided the most consistently positive results, regardless of the size of the cartridge or converter. Surprising, because that ink is generally not known for superior performance or outstanding characteristics, but I’ve had no ink flow problems with it in any of my pens.
Writing with the Pocket Pen is a very “forgettable” experience, and I mean that in the best way possible. Provided you fix or don’t have any ink flow problems, the Pocket Pen is very smooth and consistent, allowing you to concentrate on what you’re writing rather than constantly fidgeting with your writing instrument to get it to write. After finding the perfect ink for your needs, this pen will most likely outlast you 🙂, even with daily use.

Superbly built and balanced

A phenomenal pen, wonderful balance from the material choices with the weight leaning slightly to the front. Great ink flow though I have no doubt an ebonite feed would have improved it. Arrived with quite a scratchy extra fine but I sorted that with little effort and honestly there is simply no beating the unique filling system or the absolutely perfect engineering and tolerances evident in Roy’s creation. Puts all else to shame (except maybe Gravitas of course).

Emy and the team were fantastic in arranging the shipping to perfection and keeping me informed himself throughout!

Fantastic Pen!

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.
