Product Description

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.

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

The BEST Pocket Pen I've Ever Used.

Unbelievably small when capped, this pen compromises little to give a full-sized writing experience when in use. The feel is all quality; good weight, great grip, smooth threads, and the no 6 nib makes ink flow absolute perfection every time. The one compromise made here is that the pen is so small, you're not going to be using a converter here. Just standard international short cartridges. I understand eye-dropping is also an option, but I won't be doing that, so I won't speak to it. What I can confidently say is that this pen impressed from minute one and continues to be a joy to write with and carry. I've paired mine for the time being with J. Herbin Perle Noire ink cartridges and it writes like a dream.
