Description

Precision Engineering. Radical Innovation. Timeless Design. The Monster

Don't be misled by the name, The Monster is not an oversized fountain pen. It’s a thoughtfully crafted writing instrument, inspired by the classic Gravitas Vac silhouette and refined with modern engineering. Every curve, every proportion has been carefully considered to create a fountain pen that feels bold yet perfectly balanced in the hand.

Disclaimer ! - the combination of the sleek finish and the lack of the clip makes this pen to easy roll off the table/desk or slip off the pocket while in carry, the result of such unfortunate events can be a pen barrel cracked and/or split where the clear acrylic meets the aluminium section threads. Such unfortunate accidents are not covered by warranty !

Machined from solid Grade 5 Titanium and paired with an Optical Grade Acrylic barrel, the Monster delivers a writing experience that is both substantial and effortless. Its weight have been optimised and increased from the Aluminium version, offering a solid feeling and comfort without compromise. The TiSiNx coating is a blend of silicon nitride and titanium nitride, offers resilience and it exhibits a rich deep blue/purple hue. The cap is featuring a inner Delrin sleeve which allows for a smooth posting and a smooth feel in capping and uncapping - aiding in the sealing of the nib inside the cap.

At the core of The Monster lies the Kraken Filling System, a revolutionary filling mechanism born from a surprising source: medical device research. While developing retractable pens,  Ben Walsh the lead designer of Gravitas explored shut-off valves and sealing solutions used in mechanical devices - heart valves. The result? A precision-engineered system that offers reliable and efficient operation, vacuum integrity and a unique tactile experience that sets it apart from traditional vacumatic filling systems.

When installed in The Monster - Kraken Filling System brings a huge ink volume of 7ml of ink at full load (full Namiki Emperor ink load - 6ml ink) and an outstanding vacuum integrity due to the use of specialised quad ring* (*a two contact point square ring which maintains a lubricant in between contact points ensuring constant lubricant delivery each time when used) translating in a efficient suction of ink with even one plunge.

The writing point of The Monster is a steel size 8 nib paired with an ebonite feeder - available in 4 sizes : Extra Fine, Fine, Medium and Broad. 

Monster is more than a writing instrument. It’s innovation you can feel, in every detail, every line, every word you write.

Excellent pen but be CAREFUL

Had the pen for three days and absolutely fell in love with it, it is smooth, writes instantly well, etc. Be careful though, the clip is stiff and wasn't grabbing well to my pocket, and when I bent over, it popped out, hit the floor and the barrel shattered. Very heartbroken.

It's even more beautiful in person and and feels like an engineering marvel.. The nib is sublime. I've been writing with this regularly and have not come close to needing to refill. Kudos to Ben Walsh for creating this!

A marvellous pen

First time order and I was overwhelmed how quickly it was processed and shipped. Got a broad nib and it's pure joy to write with this pen every single day since having received it.

The best of the best

This pen is just superb. I own and also love all the versions of the Monster. I have all aluminium ones and also all titanium versions with different nib variations. and I have to tell you this is the best and the las tpen you will ever need. the only person i would not recomend this pen to is someone wwith really small hands because this pen is a monster. but monster in a good way. even my mom likes it and she does not have big hands.

pros: easy to do super fill and the ink capacity is extreme. All nibs are amazing. with EF nib this pen could write forever with that capacity. ale it looks amazing and the titanium tisinx version is just extremly good looking.

cons: I am addicted to these pens :D

My favorite pocket pen!

I've tried almost all of the pocket fountain pens out there, especially the ones with a #6 nib, and this Quark is my favorite of the bunch.

The material choice in a stone wash finish is perfect for a pocket pen. It provides good texture to grip and handle the pen, which you will be doing a lot because you need to unscrew to uncap and then screw to post... and then again in reverse to put the pen away. But the zing! of the zirconium makes each writing opportunity such a pleasurable experience. You're able to do this quickly as well because of the minimal turns it takes manipulate the cap. The grooved texture of the grip is also excellent. Just enough to give you a good grip but never in your way. I do wish the grip section was about 1mm thicker though.

I have mine fitted with a Pilot #15 nib and eyedroppered. I smile every time I take it out of my pocket... the zing... the reveal of the 14k Pilot nib... the perfectly textured groove section. The whole package just comes together so lovely!

If I had to complain though, my one gripe is that when posted, the cap wiggles ever so slightly. It's very minor, but you do feel it move in your hand when writing from time to time. Also, mine takes about 1.5 rotations to uncap, but the description says 0.6 turns. On the plus side, it can post in 1.5 turns, even though the description says 2 turns. Not sure if this is just a variance in manufacturing.

But overall this is an amazing pen. I have been eyeing it for over a year and now I wish I had gotten it sooner.
