Gravitas Sentry Fountain Pen in Full White Delrin

The Sentry is Gravitas' bigger take on its entry-level pen, and the extra heft sits well in the hand. A balanced, weighted section keeps it comfortable over long writing sessions, even though it's a touch heavier than the smaller model it grew out of.

Its cap runs on triple-start threads, so it comes free in just 2.25 turns.

Everything is machined from Delrin, a material picked for its strength and durability and for a low coefficient of friction that makes it wear proof. Delrin also resists chemicals, which suits inks that need a thorough cleaning routine. If you like eyedropper fills, this is a great platform for the conversion.

The section measures 25mm in length and tapers from 13.25mm to 11.5mm in width, cut from Delrin with micro-machined grooves that give you a secure hold while writing. Up front sits a Gravitas-made size 6 steel nib, compatible* with Jowo No. 6 threads, fed by an ABS plastic feeder. Nib options run Extra Fine, Fine, Medium and Broad. A standard international converter ships with every Sentry fountain pen.

*Fitment of any replacement nib is your responsibility when you swap units - we can't be held responsible for damage caused by using non Gravitas nibs or nib units.
