Product Description

Gravitas Sentry Polycarbonate Fountain Pen

Introducing the Sentry fountain pen, the larger sibling of Gravitas' entry-level model. While slightly heavier than its counterpart, the Sentry remains comfortable and user-friendly, thanks to its balanced, weighted section. The cap, equipped with triple-start threads, disengages effortlessly with just 2.25 turns.

Machined from a solid rod of Polycarbonate, known for its strength and durability, this material can withstand significant impact without cracking or breaking. Despite its strength, polycarbonate is lightweight compared to materials and heat resistant. With a satin/frosted texture it shows the inner works of the Sentry and when is converted to an eyedropper shows the ink color in a unique way.

Measuring 25mm in length and tapering from 13.25mm to 11.5mm in width, the section is expertly crafted from 304 stainless steel, coated with CrN and adorned with micro-machined grooves for a secure hold during every writing session. The Sentry is equipped with a Gravitas-produced size 6 steel nib, compatible* with Jowo No. 6 threads, and an ABS plastic feeder, offering a range of nib options including Extra Fine, Fine and Medium. To further enhance your experience, each Sentry fountain pen comes with a standard international converter.

Elevate your writing journey with the exceptional craftsmanship of the Sentry fountain pen.

Customer Comments
"The nib has the slightest amount of feedback without being scratchy (EF nib). It's neither a gushy nor a dry writer. It doesn't skip or have hard starts. The clip has a moderate amount of give. The cap takes about 1 1/2 turns to remove. It's quickly becoming the pen I most often use." - Verified Buyer, January 2026
