Gravitas Fountain Pen - Quark - Torlon

Introducing the Quark, a pocket fountain pen that revolutionizes compact convenience without sacrificing performance. This version is crafted from a durable blend that incorporates PTFE (Teflon) and graphite - Torlon. This combination offers natural lubrication, along with enhanced chemical and wear resistance, outperforming Ultem in mechanical properties by nearly 30% in certain aspects.

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 double-start cap threads offering a smoother capping and posting action, increase wear resistance and improved seal, the Quark’s nib is revealed with just 0.6 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, Medium, and Broad.

*when swapping for a different nib unit you are sole responsible for checking the fitment of the new nib - we are not responsible for any damages that may occur from the use of non gravitas nibs/nib units.

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

Elevate your writing experience with the Quark Pocket Pen, where compact design meets top-tier functionality.
