Four Fountain Pens Worth a Spot in Your Rotation: Gravitas, Lambrou, and Armando Simoni Club

Introduction

Every month brings a chance to rediscover pens that have earned a permanent place in the rotation. This lineup mixes brand-new releases with pens that have years of history behind them, and each one offers a very different writing experience. From an in-house steel vacuum-filler to a large Arco celluloid flex-capable pen, here is what makes these four worth a closer look.

Gravitas Vac 2.0

The Gravitas Vac 2.0 is a beautifully made pen built from Ultem, aluminum, and PVD-coated stainless steel. The standout detail is the nib: it is made in-house by Gravitas, and it skips the traditional breather hole in favor of a longer slit, which gives the tines a bit more responsiveness. You can push gently on it for some line variation, though it should not be treated like a vintage flex nib.

The vacuum-style Kraken filling system holds a genuinely large capacity of ink, and the translucent barrel lets you watch the mechanism work. The aluminum cap and turning knob paired with a stainless steel section give it a slight forward weight balance. It is a pleasant, easy writer, and a really fun pen to use day to day.

Lambrou Pens LB6

The Lambrou Pens LB6 is a stellar pen and, for many collectors, a favorite of all time. This is number six of ten in the cayenne flame red material, which ranks among the prettiest pen materials ever made. The faceted version is especially striking: the facets bring out the depth of the material beautifully as light moves across them.

It is a large pen fitted with a Bock 380 number eight nib unit in 18K medium. The line it lays down is on the finer side for a medium, with a very thin stroke and noticeable feedback that sounds scratchier than it actually writes. It is a gorgeous, expressive pen that rewards slow, deliberate writing.

Gravitas Sentinel

The second Gravitas in the lineup is the Sentinel, in a raw titanium finish. It is a wonderful example of restrained design: simple, minimalist, with no clip and a very straightforward silhouette. The fine machined grooves on the section add grip security, so the pen never feels slippery, and the titanium material has a lovely weight that makes it feel solid in the hand.

The number six stainless steel nib in broad is not flashy in terms of features, and that is the point. This is a beautiful and simple pen that just writes nicely. It feels really solid, and it is a genuinely pleasant everyday writer.

Armando Simoni Club Bologna Extra

The Bologna Extra from the original Armando Simoni Club era is a truly big pen in Arco celluloid, with the material’s characteristic chatoyance catching the light in a way that photographs struggle to capture. It dates back to the DC Pen Show 2012 launch, and it remains one of the most beautiful large pens around. With its brass liner, it is quite heavy, so it suits writers who enjoy a substantial pen.

The 18K medium “magic flex” nib has a bit of springiness, helped by an interesting two-part feed: the front section can lift slightly with the nib to help prevent railroading. It is best described as springier than average rather than a wet noodle, but it produces expressive line variation when guided gently. The filling system uses an internal sack-style design reminiscent of a Chilton filler. One practical note: with dye-heavy orange inks, some harmless nib crud can build up, so a quick clean keeps things tidy.

Overall Buying Advice

If you want modern engineering and big ink capacity, the Gravitas Vac 2.0 is the clear pick. If you prefer raw, honest materials and a no-fuss everyday writer, the Sentinel delivers that in spades. The LB6 and Bologna Extra sit on the collector side of the fence: large, characterful, and chosen as much for their materials and stories as for how they write. Matching the pen to how you actually write matters more than any single spec.

Conclusion

This lineup covers a lot of ground: an in-house steel vacuum-filler, a faceted flame-red grail pen, a minimalist titanium workhorse, and a big Arco celluloid classic. Each earns its place for a different reason, and together they show how varied the fountain pen hobby can be. Whichever direction you lean, there is something here worth trying.
