Description

Meet the 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. 

The new design of the Sentry Grade 5 Titanium TiSiNx features ACME thread profile that translates in a smooth and enhanced sealing of the nib inside the cap. The cap of the Sentry Grade 5 Titanium TiSiNx features a Delrin insert for a smooth triple-start thread that disengages in just 1.5 turns, leaving no marks from the posting action. 

The 25mm-long section, ranging from 13.25mm to 11.5mm in width, is expertly crafted from 304 stainless steel. Coated in titanium silicone nitride (TiSiNx) and adorned with micro-machined grooves, the section ensures a secure grip during every writing session. 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 and Broad.

Enhancing your experience, the Sentry comes with a standard international converter provided with each fountain pen.

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

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!
