Gravitas Quark Grade 5 Titanium Fountain Pen

Introducing the Quark, a pocket fountain pen that combines compact convenience with exceptional performance. The pen is entirely machined from a solid bar of grade 5 titanium - cap / section / barrel.

Designed to be the smallest pen of its kind, the Quark transforms into a full-sized writing instrument when posted. Its lightweight construction and ergonomically balanced section provide a comfortable and effortless writing experience.

With the new ACME triple-start cap threads offering a smoother capping and posting action, increase wear resistance and improved seal, the Quark’s nib is revealed with just 0.5 turns, and the cap securely threads onto the back in only 2 turns when posted. The 22mm-long section, tapering from 9.85mm to 9.0mm, is precisely engineered from grade 5 material, featuring micro-machined grooves and a bead-blasted finish for optimal grip.

Fitted with a Gravitas-produced size 6 steel nib, compatible* with Jowo No. 6 threads and an ABS plastic feeder, the Quark offers a range of nib options including Extra Fine, Fine, Fine Flex, Medium, and Broad.

This pen is also eye-dropper friendly, capable of holding up to 1.5ml of ink or accommodating a standard international ink cartridge.
