Description

Gravitas - Dinkey is a combination of its pocket-sized form scaled down to that of a quark. Refined and practical - the Dinkey consists in the sum of lessons learned throughout the years from previous models of Gravitas and brings out the very best in design, choice of materials and craftsmanship.

The fountain pen is small, portable, and handy, placing emphasis on the material from which it is made. It showcases a unique range of materials that, up until now, have not been offered in the Gravitas lineup. The Carbon used for the Dinkey Carbon X is a unidirectional structure carbon, when used for the Dinkey shape the material shows a unique scale patter - material is untreated and the exposed texture is a satin one. 

The Dinkey Carbon X is a eyedropper filler only (doesn't fit a ink cartridge or converter) inner cap and barrel comes lined with Delrin in order to contain the ink and seal it, the section is made from stainless steel, compatible* with a Jowo size #6 nib unit. (standard-generic steel Jowo nib unit).
*Please note that only a Gravitas-supplied nib should be used with this pen; other brands may not fit and could be damaged. When swapping for a different nib unit you are sole responsible for checking the fitment of the new nib - we are not responsible for any damages that may occur from the use of non gravitas nibs/nib units.

Dinkey Carbon X Eyedropper offers a 1ml ink volume which its recommended to not be exceeded for optimal performance in use and carry. 

The writing point of the Dinkey is a Gravitas steel 6 nib, available in extra fine, fine, medium, and broad - powered by a ABS plastic feeder. Each Dinkey Carbon X comes with a 1ml pipette.

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

What a cool little pocket pen!

Not only is it cool, I just love this awesome carbon texture! And the attention to detail with the red ebonite feed and red logo, it’s a work of art. And the attention to detail and army’s personal letter makes a customer feel for certain this is the place to buy pens!

Charming pen, great material

This is my second carbon Gravitas pen and I love this material. The steel section compensates the lightness of the body beautifully. Writes like a charm, but required me to pull out the feed and nib out of the socket since it wouldn't write after a simple flush. A very stealthy pen, it is not likely to be a conversation piece unless you actively want to show it off. As can be seen in lots of images, the grain of the cap and the body mostly line up when the cap is screwed on, which is an appreciated attention to detail.
Thanks to the teams at Gravitas and Pen Venture.

Dinkey Carbon X

I love small pens with a large nibs. This pen is well made and finished (down to lining up the Protruded Carbon relative to the nib). Hard to believe that this Dinkey opens up to a full size pen. It’s a great addition to the carbon fiber line up.

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!

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.)

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!

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!
