Description

An ultra-portable and robust pocket pen, designed for those on the go. This lightweight fountain pen boasts exceptional durability and user-friendly features, including a Delrin section for effortless handling. Delrin is Polyoxymethylene (PMO) and it combines low-friction and high-wear resistance with the high strength and stiffness such applications require, making it the ideal material to replace metal in designed parts.

The cap of the Pocket, with triple-start 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 Delrin for optimal weight reduction. 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 Fine flex, 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.

A great pocket pen

A wonderful pen - I like the pure white color. Nib can be easily exchanged for different JoWo nib. Can be eye-droppered and can see enough through the Delrin to see if there is sufficient ink. I can't really decide whether I like the Ultem or Delrin more, but the Delrin is more attractive and sinuous to touch. Great shipping and communication with Emy.

Fantastic Experience with Pen Venture - Love My Gravitas Pocket Pen!

I recently purchased a Gravitas Pocket Pen in Delrin from Pen Venture, and the entire experience was nothing short of excellent. The pen itself is a joy to use—lightweight, comfortable, and durable, with a sleek design that’s perfect for everyday carry.

What really impressed me, though, was the service from Pen Venture. The shipping was incredibly fast, and my pen arrived in perfect condition. I was also pleasantly surprised to find a personal note from Emy included with the order—a thoughtful touch that made the purchase feel special.

Overall, Pen Venture delivered great customer service and a high-quality product, and I wouldn’t hesitate to shop with them again. Highly recommended for anyone in search of unique and well-crafted writing instruments!

Sheer Ecstasy

I received my new pens, and first from Gravitas, less about an hour ago. My love for this brand began with a conversation with Ben Walsh himself in November 2022. I was disappointed to learn he does not ship to my part of the world, Kenya, to be precise in East Africa. However, my love for pens led to me to Pen Venture YouTube page. I decided to check their site and voila! I placed my first two orders. I cannot speak enough about the nondescript package I have received. The service has been excellent and Emil's note a fantastic touch. I have every intention of placing more orders in days to come. Thank you!

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.

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

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.

Gravitas #6 extra fine nib

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!
