Description

Introducing the Gravitas Micarta - Red Linen fountain pen, a distinctive iteration inspired by the beloved Sentry pen design. This version features a unique twist with micarta sleeves seamlessly integrated into its structure. Crafted for a feather-light feel, the fountain pen boasts a stainless steel section complemented by inner sleeves made of 6061 aluminum. The section spans 25mm, tapering from 11.9 mm at its widest to 10.3 mm at its slimmest, providing ergonomic comfort.

The 304 stainless steel section is thoughtfully designed with micro-machined grooves for enhanced grip. The pen is equipped with a Gravitas nib, featuring Jowo no:6 threads and offering options in extra fine, fine, medium, broad, 1.1 stub, and 1.5 stub. Accompanied by a specially designed pen sleeve and a standard international converter, this pen is versatile and convenient for your writing needs. Additionally, it can be posted for added flexibility.

Please be aware that the micarta material may absorb oils and moisture and is susceptible to ink staining. Over time, it develops a unique patina with use, which can be cleaned with soapy water. For a vibrant blue micarta pen, simply dip it in baystate blue ink to personalize your writing experience!

Elevate your writing journey with the refined craftsmanship of the Sentry fountain pen.

Excellent Fountain Pen

The Gravitas Sentry in Micarta is everything I expected and more!

I love the material, craftsmanship, the feel of the pen and especially the the way it writes - Super smooth and sensitive.

I can highly recommend Pen Venture - Great products and pricing, fast, reliable international shipping and outstanding customer service. Who doesn't appreciate a handwritten thank you note from the owner??!!

Aslo, shout out to Mick L/The Offstage Me Pen Reviewer and YouTuber for the thorough Gravitas Sentry Micarta review and for recommending the Pen Venture as trusted and knowledgable online retailer.

Gravitas - Vac 2.0 Aluminium | Black
Andreas Andersson
Substantial, reliable, and smooth

The Gravitas Vac 2.0 is an amazing tool for handwriting. The nib is smooth, distinct, and reliable, and it has some weight due to its durable materials, black aluminium/aluminum and ultem, the perfect combination of a tool which will survive most of us, still functioning if the internal vacuum piston system is cared for. I have enjoyed this fountain pen for seven days and I am pleased to say it is one of my better ones, and it is fun to use. I recommend it.

(Emy was correct: The nib has great flow, about six drops of ink will automatically flow from the nib after I have just filled it, after that no problems; tissue paper or the ink bottle under the nib until that happens is recommended, other than that: an excellent fountain pen.)

Gravitas - Vac 2.0 Aluminium | Black

FANTASTIC !!!!!

What a fantastic pen—and customized too!

It writes beautifully and arrived surprisingly quickly, even though I’m in Canada. This is my third order from Pen Venture, and once again, the experience has been outstanding. It's always a pleasure to come back.

My Gravitas arrived perfectly tuned and was ready to write straight out of the box. I filled it with Pelikan Royal Blue, and from the very first stroke, it was smooth, consistent, and an absolute joy to use.

I own several excellent fountain pens, including a Pilot Custom 823, a Sailor 1911, and a Leonardo Momento Zero, and I can honestly say that this Gravitas holds its own among them. It is remarkably well made and comes very close to being the perfect writing instrument.

A big thank you to the entire Pen Venture team for the exceptional service, careful tuning, and attention to detail. I’m already looking forward to my next order!

Gravitas - Vac 2.0 Aluminium | Black
Cosmin R.
A Worthy Sequel to an Awesome Pen

On its own, this pen feels very durable and premium, and the bead-blasted, matte black coated treatment gives it a very “professional” vibe. The Fine nib is bouncy and smooth, very usable on the underside as well (with added feedback, but not scratchy), the ribbed steel grip is very comfortable, the feed holds a lot of ink on its own, and the reservoirs behind it will keep it in writing condition for dozens upon dozens of pages after a fill.

The cap screws open and closed smoothly, with a very satisfying click at the end when closed; it posts deeply, and it also posts securely after being pressed down slightly on the barrel. It is light enough that it does not back-weight the pen significantly when posted.

The barrel construction, along with the newly-implemented Kraken filling system, ensure a significant amount of ink is pulled in from the first try. Much like the main cap, the blind-cap screws open and closed smoothly for refills or ink transfers between reservoirs.

Compared to its predecessor:
Fewer transparent areas overall, but the Vac 2.0’s structure feels more solid than the Ultemate Vac.
The body thickness and thread profiles are different on the Vac 2.0 than on the Ultemate Vac, no mix-and-match potential here.
The matte black coating gives the pen a more refined, premium feel on the metallic parts.
The inner lining of the cap doesn’t get stuck in the barrel thread as often, and when it does, it either slips back into correct position, or it is easier to unscrew and reposition, without the metal thread eating into the cap material.
The coated, no-breather-hole design of the new Gravitas steel nib may not be to everyone’s taste, but I like it a lot, and functionally, this nib feels more bouncy and polished, with smoother writing than its predecessor.
The feed seems to pick up a lot more ink on its own from just a 5-second dip, and the small reservoir behind it looks to have more capacity to back it up before needing to unscrew the blind cap and refill it from the large reservoir.
The Kraken filling system seems to suck up significantly more ink per pump than the mechanism from the Ultemate Vac.

Overall, a very well made fountain pen, and a thorough refinement to an already excellent design. Very satisfied with this purchase!

Great Little Monster

Wow!
Just like the Monster but thinner. For me it is more comfortable for longer writing sessions. The filling system is stellar. Holds lots of ink. As always Ben Walsh and Emy have delivered a innovative and enjoyable writing experience. Can't wait to see what's next. Keep up the wonderful work!
