Gravitas Ultemate Vac Fountain Pen Polycarbonate

Gravitas Ultemate Vac is a revolutionary design and Gravitas' first foray into advanced filling systems. This fountain pen sets a new standard for durability by integrating titanium in critical areas, addressing the common weaknesses found in other vacuum pens.

Machined from medical grade clear Polycarbonate, known for its strength and durability, this material can withstand significant impact without cracking or breaking. Despite its strength, polycarbonate is lightweight compared to materials and heat resistant. 

Crafted with an emphasis on long-lasting performance, the Ultemate Vac uses exceptionally durable materials, with titanium strategically placed to reinforce vulnerable points where other vacuum pens often fail. Despite its sturdy build, the pen remains lightweight, featuring a transparent Ultem section that allows easy monitoring of ink level in the secondary chamber.

With a generous ink capacity of over 2.5ml, plus an additional 0.7ml in the secondary chamber, the Ultemate Vac ensures long, uninterrupted writing sessions. The second chamber is equipped with a shut-off valve. When you fill the pen, you fill both ink chambers. Once the ink close to the nib run out, you need to unscrew the end knob to continue writing. For optimal ink flow, it’s recommended to unscrew the end knob during use for a consistent, wet line.

Gravitas Ultemate Vac Polycarbonate is equipped with a #6 steel nib designed and manufactured by Gravitas.
