Fountain Pens
Gravitas Pocket Pen Copper: A Heavyweight Pocket Pen With Real Character
An uncoated raw copper pocket fountain pen with a Delrin-sealed cap, roll stop, and a number six steel nib. Here is what works, and what to consider before buying.
Introduction
The Gravitas Pocket Pen in raw copper is a small pen with a big personality. It is uncoated copper, which means it starts developing patina almost immediately, and that is exactly the point: this is a pen meant to be used and to show its use. At €120 it is not a casual purchase, but the precision of the machining and the thoughtfulness of the details make a strong case for it.
Who This Product Is For
This is a pocket pen for people who like substantial writing instruments. It weighs 79 grams, which is heavy for its size, and that is a direct consequence of the copper construction. If you prefer light pens, you can pass this one by without a second thought. If you enjoy the feel of a solid, dense writer, there is a lot to like here.
Design and Materials
The pen ships in a simple cardboard box with a paper sleeve and a small pen bed. Most of it can be recycled, which fits the no-nonsense character of the product.
The cap features a flat facet on top, which doubles as a roll stop. A small round pen with no clip would normally roll straight off a desk, and this facet solves that problem brilliantly. The cap also has an inner Delrin sleeve, which improves the cap seal and provides a surface for posting or capping. Acme threads and a triple-start cap mean uncapping takes about one and a half turns.

The Gravitas logo sits on the cap, and the barrel ends in a pointed finial. Compared to a Pilot Metropolitan, the pen is smaller, which is exactly the intention: it is a pocket pen first.
Nib and Writing Experience
The pen uses a number six steel nib, available in extra fine, fine, medium, or broad. A number five would have been adequate for a pen this small, but the number six looks proportionally excellent and gives the pen a confident stance on the page.
The stainless steel section has micro-machined grooves that make it surprisingly comfortable to hold. They are fine enough that no ink gets stuck in them during filling, which was a genuine concern before using it.
In use, the nib produces slight line variation by default, with downstrokes a touch wider than side strokes. It is not advertised as a flex nib, and pushing it quickly leads to railroading, so treat it as a firm nib. Reverse writing is possible, though noticeably drier and not scratchy.
Everyday Use and Patina
Unposted, the pen is too small for most hands. Posted, it becomes a genuinely comfortable writer, though the heavy copper cap makes it somewhat top-heavy. The flat facet can be angled to rest naturally against the hand, which helps.
One practical note: the supplied mini converter uses a simple push-pull system. During testing, ink occasionally stalled at the top of the converter due to surface tension, and a quick clean with diluted dishwashing detergent resolved it. This is worth keeping in mind as basic maintenance rather than a dealbreaker.


The raw copper patinas fast because there is no coating at all. Areas that get handled show it quickly, while untouched spots stay brighter. If you find that charming, you will love it. If not, this is simply not the pen for you. The patina can be polished away if you change your mind, and a light copper smell is possible with extended handling, though the section itself is stainless steel rather than copper, which limits it.
Things to Consider Before Buying
Price is the most common objection: €120 for a small pen with a steel nib is a real sum. The counterargument is the precision of the machining and the sheer number of small things done well, from the Delrin cap liner to the grooved section.
Weight is the other one. This is a downright heavy pen, especially posted, and there is no way around that. It is a defining characteristic, not a flaw, but it will not suit everyone.
Buying Advice

Buy this pen if three things are true: you like heavy, solid writers; you enjoy living finishes that change over time; and you want a genuinely pocketable pen that still posts into a full-sized writer. If any of those fail, look elsewhere, because the copper character is the whole appeal.
Conclusion
The Gravitas Pocket Pen in copper is a meticulously designed small pen that rewards daily use. The roll stop, Delrin-sealed cap, grooved section, and oversized number six nib all add up to something greater than the sum of its parts. Accept the weight and the patina, and you get one of the most characterful pocket pens around.
