Gravitas Quark Orange

The Quark is a pocket fountain pen that combines compact convenience with exceptional performance. Machined entirely from durable 6061-T651 aluminum (cap/section/barrel) and anodised with a bead blasting finish. Quark Orange and Shamrock Green are part of the 2025 release which brings the ACME threads for capping and posting. 

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. 

Fitted with a size 6 steel nib, compatible* with Jowo No. 6 threads and an ABS plastic feeder, the Quark offers a range of nib options.

*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.
