Description

An ultra-portable and robust pocket pen, designed for those on the go. The section is crafted from 304 stainless steel, coated in Black PVD, and designed with micro-machined grooves to enhance grip. ULTEM resin is a high performance polyetherimide thermoplastic (PEI) - used in the manufacturing process of circuit boards, sterilisation equipment and most notably in the making of aircraft parts, it offers high strength and stiffness, a broad chemical resistance, making it expensive and used for only high demanding applications.

The cap of the Pocket, with double-start ACME threads, smoothly disengages in just 1.5 turns, and one side is expertly machined flat to serve as a practical roll stop. Posting the Pocket makes up for a full size writing instrument when in writing.

The 25mm-long section, ranging from 11.85mm to 9.8mm in width, is crafted from metal. Micro-machined grooves enhance grip, ensuring a secure hold, offering a comfortable yet firm stationary grip while writing with the Pocket.

The fountain pen is equipped with a Gravitas-production size 6 steel nib and abs plastic feeder compatible with Jowo No. 6 threads, providing a range of writing options, including Extra Fine, Fine, Medium, and Broad. With every Pocket fountain pen comes included a standard international cartridge converter, if in need of more ink, the Pocket comes with rubber orings in order to be an ideal eyedropper fountain pen, taking advantage of the entire barrel volume for ink.

Elevate your writing experience with this compact and resilient pocket pen.

What a great company to do business with

Pen Venture responded to my questions very quickly and thoroughly. The shipping was excellent and reasonably priced. My Gravitas ultem pocket pen is a jewel, meeting my high expectations. Thank you Pen Venture

Terrific little pen

Attractive, writes well, made well. Only surprising thing is that it takes more force than I expected to post cap. I'm not sure if the caps fits into a ridge or is just friction fit when posted. I believe the pen is well worth the money.

Pocket Perfection

Thank you to Gravitas and Pen Venture for a fantastic start to my 2025 pen year! This is my first pocket-sized fountain pen - I’m not sure why I waited so long to acquire one, but waiting until now was clearly meant to be. The Pocket Ultem is a beautiful pen. Small but mighty, it’s an excellent writer, a very pratical pen that is just plain fun to use. You can’t help but appreciate its compact, sleek design, smooth finish, satisfying weight and comfortable feel in hand. I am delighted with my purchase and can see another Gravitas pen on the horizon!

And a word about the customer service. I was enticed by Emy's videos, and did a bit of research about Gravitas and its line of pens. I was impressed by what I read and heard and looked forward to giving Gravitas a try - it sounded promising! The pen I ordered delivered on all counts, and the delivery itself was fast and without a hitch. The pen pouch and Gravitas notepad were nice touches to round out a very pleasant customer experience with Gravitas and Pen Venture. Kudos to them.

Blown away

My favorite EDC for years has been an Ensso pocket pen. I’ve tried so many pens to find something I loved more but was often disappointed by manufacturing, design, materials, size, or something else. Just for this Gravitas and was completely blown away. Love the material. Machining precision and details are just out of this world. Literally the only been I’ve reached for all week. Also Pen Venture has seriously fixed the shipping issues famous to this brand. Bravo to them for shipping so dang fast I thought there had to be a mistake when my email said my pen had arrived.

Gravitas - Vac 2.0 Aluminium | Black

Gravitas Vac 2

The construction of the Vac 2 is flawless. The textures of the materials and it's simple lines display an elegant beauty. The large steel nib delivers a pleasant writing experience and also provides a bit of flex.

Gravitas - Vac 2.0 Aluminium | Black
Chris

Amazing Pen! Gravitas makes one of the best piston fillers out there. I dont keep the nib and normally use the pen for coustom flex nibs with Jowo #6 compatible nib units. So, i really cant speak on the nib. However, this pen is just built with high quality components. The weight, feel, and overall aesthetics are unmatched. You wont find better at this price point.

Platinum - #3776 Century Kaga Maki-e Sansui GT
Robert Moore
Platinum Sansui - Smooth Operator

I recently acquired the Platinum Maki-e Sansui pen in a Medium nib. The Pen Venture team was kind enough to carefully inspect and tune this pen before sending it on to me. Many thanks for that. It writes very smoothly and with a steady flow of ink. The Medium nib is my favorite nib configuration from the Platinum brand. The line width is nice and thin and always writes consistently right of the box. This lovely Maki-e pen was no different. I highly recommend it.

The extra fine nib came tuned to perfection—a joy to write with. Thank you Emy!

Gravitas - Vac 2.0 Aluminium | Black
Jimmie
FANTASTIC!

The VAC 2.0 is a great improvement to an already great pen (the original VAC Ultem). The weight and balance are spot on. The cap and the new threads engage without hesitation. No missed closures and the cap has a nice stop when threading back on. It posts securely without issue. Filling with the Kraken system is easy. I got a medium nib and it is smoooooooth. Mine is on par with my 823 medium nib The smoothness, wetness and bounce would make you think it's a gold nib. Line width is slightly narrower than the 823 medium. The pen feels solid and well built. I'm not worried about this one getting knocked around. Overall a great pen. Shipping from Pen-Venture to Colorado was five days! Great pen and service all around!

My wonderful first Titan pen

Beautiful colour. The nib is smooth and wet. The grip section is textured, I will not worry about writing with it in hot weather. This is my first demonstrator pen, I love watching the ink level drops (very slowly) in the barrel. The package is packed very securely. Thank you staffs at Pen Venture.
