Gravitas Quark Grade 5 Titanium Pocket Fountain Pen

Machined from a single solid bar of grade 5 titanium, the Quark covers cap, section and barrel in one material. It's a pocket fountain pen built to stay compact, then turn into a full-sized writer once posted.

Weight stays low and the section is ergonomically balanced, which keeps longer sessions easy on the hand.

New ACME double-start cap threads bring a smoother capping and posting action, more wear resistance and a better seal. The nib appears after only 0.6 turns, and posting takes 2 turns. Machined from grade 5 material, the 22mm-long section tapers from 9.85mm to 9.0mm, with micro-machined grooves and a bead-blasted finish for grip.

Up front is a Gravitas-produced size 6 steel nib, compatible* with Jowo No. 6 threads and fitted with an ABS plastic feeder. Choose Extra Fine, Fine, Medium or 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.

Fill it as an eyedropper with up to 1.5ml of ink, or use a standard international ink cartridge.
