Gravitas Sentry Ultem

The Sentry fountain pen, isthe 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. 

Machined from a solid rod of medical grade Ultem, known for its strength and durability, this material can withstand significant impact without cracking or breaking. Despite its strength, Ultem 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.

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 size 6 steel nib, compatible* with Jowo No. 6 threads, and an ABS plastic feed. To further enhance your experience, each Sentry fountain pen comes with a standard international converter.

*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.
