Description

Meet the upgraded Sentry fountain pen, the larger sibling to the entry-level model from gravitas. While slightly weightier than its counterpart, the Sentry maintains a comfortable and user-friendly design, thanks to its weighted section. With triple-start ACME cap threads, the cap effortlessly disengages in just 2.25 turns. Sentry Raw Brass comes uncoated and untreated letting it age* according to use and handling - this is a natural process of the Brass and makes your pen unique to yourself.

*due to the nature of the material this pen may arrive to have some more or less patina showing (this is not a valid condition aspect for a call on warranty or considering it used - its a reversible process that you can address by polishing this pen with a jewellers cloth and maintain it shiny)

Constructed from 304 stainless steel, the section is black PVD coated and features micro-machined grooves for an enhanced grip. To prevent marks from posting - the cap features a delrin sleeve and the upgraded Sentry series now comes with two o-rings, one on the section and one on the barrel, enhancing the experience while carrying and using the pen - preventing the accidental uncapping or untwisting of the section.

Equipped with a Gravitas-production size 6 steel nib compatible with Jowo No. 6 threads and abs plastic feeder, the Sentry offers versatile writing options, including Extra Fine, Fine, Medium, Broad and Fine Flex.

Enhancing your experience, the Sentry comes with a standard international converter provided with each fountain pen. Sentry Raw Brass is not eyedropper friendly - being a raw and exposed metal, it is not recommended to be converted to eyedropper filling system.

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

Hammer time!

I bought the pens to customize to my liking using a dremel tool for a hammered finish. Although a bit heavy (something to keep in mind, brass pens are on the heavier side) it feels great in hand and writes beautifully.

Unapologetically Brass

Brass was actually one of the earliest alternatives to Ebonite when fountain pens were the only game in town. As a matter of fact, many modern fountain pens (and Biro pens) still have a brass body, but they hide it under paint or lacquer. Brass is an ideal metal for pen makers, because it has a relatively low melting point, is easy to shape, and relatively corrosion resistant. But...copper has a strong smell when it comes into contact with fingers. Brass is 80%-90% copper, so you get that smell with brass, as well. The good news is that you may not care much for the smell of copper, but many microbes find the presence of copper to be absolutely fatal. And after a couple of weeks to a couple of months, depending on how frequently you use the pen, the smell will be almost completely gone. The microbe-killing part will still be there, without the smell. As far as writing with this microbe killing weapon of mass decontamination, it's nearly perfect. The Gravitas produced nib is very smooth, and it's as good as, or even better than, an equivalent sized JoWo (or Bock) steel nib. I have several Sentry pens, and the feeds on all of them are nice and juicy. If you find that your pen is too juicy, try using Pelikan 4001 Königsblau ink, which is rather dry. The metal body is free of blemishes and scuffs, but that won't stay like that for long, especially if your pen comes into contact with other metallic objects. So, if you want to keep your pens looking like new, make sure to store them in the provided carrying case when you're not actively writing with them. For me, I don't mind that scuffs and scratches, because they all add to the "lived-in" look of objects and that are not only treasured, and loved, but used daily!
Would definitely buy again.

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.

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!
