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
Richard L Sherman
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!
