Gravitas - Dinkey Cupronickel

This Dinkey has treated me well. I've been carrying it on me for a few days now and am quite happy with it. I got an extra fine nib and it writes pretty wet, if you like a regular fine then go with the extra fine. Regardless, the nib seems well tuned. Not once yet have I seen it dry start.
The pen feels great in the hands, pleasure to use. The only thing I find that slows me down is when I post the cap, sometimes I don't push it down firm enough- since it doesn't screw or snap into place- and the cap gets loose as I try to start writing. Not a big deal for me personally, but one might consider the Quark to avoid that (or just stop handling it like a pansy like I should).
All in all, this is a very solid pen and a relatively lower cost but high quality option if you want a fancy pocket sized writing instrument. If you'll excuse the poor handwriting, I also took an image of some scribbling I did to give an idea of what the nib writes like.
Shoutouts to Ben for being such a creative designer and engineer, GRMA.

I have 6 Gravitas pens now. I really want to like them, yet after 2 ergonomically pleasing but stubbornley leaking GP Pockets, my first Dinkey was the biggest disappointment: with the size of the Quark and the shape of the GP Pocket, I was hoping for this one to be the goldilocks FP, however, it proved to have the shortest life span of them all. The plastic inner sleeve, added as an improvement to protect the pen from scratches when posted, immediately got a 'fausse route' carved after posting then capping it for the first time. After capping it a few times to find 'the right groove', the section got unwound and is stuck inside it (along with the nib). Trying to het it out with a pair of pliers, is not a pleasant prospect, since that will only further damage the threads of the inner sleeve.
I guess the sleeve got bumped or warped when capping. That happened too easily. The pen is out of order in less than a week of use.
Great feel and format (5 stars), but suboptimal design, lacking in function (0 stars).

The Dinkey is my favorite pocket-sized model from Gravitas’ current line. I prefer it to the Quark and the Pocket for EDC. It’s an excellent pocket pen; beautiful and weighty, easy to maintain, writes smooth… the cupronickel material is gorgeous. It’s bright and polished, and the nickel coloring is dominant, but catch it in the right light, and copper tones will shine through. Truly eye-catching.

This is an update/addendum after the "cap mishap', specifically to thank Emy for being so helpful, kind and efficient. The speed and adequacy of having the pen picked up, fixed and sent back across borders made it feel like he was just around the corner. If that were truly the case, I would have dropped by and bought him a coffee or whisky a long time ago.
Emy's service is in a class of its own.

Let me start with addressing some complaints about this pen. Yes there is a copper smell, but everyone should know any pen with brass or copper in the body will have the smell. There are other materials available if you do not want the “coin” smell. This Cupronickel smells a lot LESS than any Kaweco brass pens.
My Dinkey has no problems posting, and the edges and threading are not sharp to me. The Dinkey is smaller than a Kaweco Sport, and has a better nib. Now my Kaweco Sports are cleaned out and sleeping in my pen case, retired.
There are not many reviews on the Gravitas Dinkey fountain pen. Good thing the Pen-Venture YouTube channel has a detailed review of the Dinkey. The Dinkey is a very compact pocket pen with an excellent #6 full size nib. I really like how the cap does NOT SCRATCH the barrel of the pen, so if you buy the Dinkey with any beautiful colors/materials, there will not be wear marks from capping the pen. I like the Cupronickel because since this pen will be in my pocket, there will be humidity and this metal alloy is very resistant to rusting.
If you are thinking about buying from Pen-Venture, be assured, this retailer is honest, has great communication, and I highly recommend.

The machining quality of this pen is second to none—it's a work of art—and the service provided by Emy/Pen Venture is fantastic. Really good communication, quick delivery and the handwritten note sent along with the pen was much appreciated. The pen also writes brilliantly straight out of the packet, with a smooth nib and no hard starts.

That said, this pen is not without its problems. For me, the biggest issue is that it is made from cupronickel. I had hoped that the marine grade quality of the material might help, but unfortunately, you are constantly plagued by a metallic smell on your hands when using the pen, just like handling coins, which are also made of cupronickel. There is no way round this as the pen is basically reacting with the oils in your skin. You might not find this so troublesome, but I really don't like the smell. Also, as other reviewers have said, it doesn't post that well, which for a pocket pen is a bit of a problem. Finally, the edges and threading on it are quite sharp, so it's not that pleasant to hold. In my view, the aluminium versions of the Kaweco Sport are much more pleasant to use as the posting is firm, the edges are rounded and there's no metallic smell.

The machining and finishing quality is amazing, threads are super smooth. Of course the fine flex nib writes beautifully too. The material is silver and very slightly yellow, think brass but way less saturated. It does have a metallic smell similar to copper (once it comes in contact with your skin), I wonder if it will develop a patina over time.

I received this pen recently to replace my EF Lamy 2000 which I had lost. The advantage is that this actually fits into my wallet. The nib writes more like a fine, but is wet and feels great on my Maruman Mnemosyne writing pad. Saying that, I would like to get an extra fine gold nib for this. I'm not sure where I could buy one from though.

The build quality is excellent and feels like a refined pen. The weight of the cupronickel is balanced and feels like a more expensive pen. I think this is a bargain at the price and there's nothing else on the market at this size. In my view, this is a better option as it push posts without and effort and feels secure.

I'm considering using it as an eye dropper as there is a o-ring seal, but I'm a bit hesitant. Is this something that you could do a video on?

I was surprised to receive a hand written note from Pen Venture - a lovely touch. Postage to Dubai was a little expensive - I think Pen Venture should consider other postal services, but it was very reliable and was received with a few days as expected.

I would highly recommend this pen.

This was my first purchase from Pen Venture and I will buy from you again for sure, smooth international delivery service!

The Cupronickel Dinkey is an excellent pocket pen that goes to full size pen posted and unlike most mainstream pocket pens the full sized section and no. 6 Nib make it an absolute pleasure to write with. The nib came tuned excellently by the pen venture team and writes wonderfully out of the box.

I can highly recommend this pen and company.

A perfectly pocketable pen with a distinct and substantial weight, a balance that gives a full size feel and an exceptionally well tuned fine flex nib. The cupronickel has been machined in a way that gives a slick feeling around the body but a fine, toothy texture along the length and a fascinating rainbow mirage over the otherwise silvery body if you catch it in the right light. The weight sits toward the palm in use and makes for a solid rearward balance encouraging the nib to glide across the page without being too back-heavy to cause any discomfort. The cap twists off quickly and easily with a satisfying metallic humm even with the liner material which allows it to be posted fast and firm without scratching the body. The section has machined grooves to provide a slip free grip without being sharp or irritating and for my admittedly small-ish hands the grip is very comfortable with it's flared end and gentle curve. The steel fine flex nib gives just a little line variation even for a lefty if you want it but if you don't it is a great fine nib for everyday writing and it arrived tuned to perfection and is now the smoothest steel nib I own.
