        Gravitas Sentry Black Fountain Pen
        
Meet the upgraded Sentry fountain pen, the larger sibling of Gravitas entry-level model. Though slightly heavier and bigger than its counterpart, the Sentry remains comfortable and user-friendly, thanks to its well-balanced, weighted section. With triple-start cap ACME threads, the cap smoothly disengages with just 2.25 turns and now features a Delrin sleeve for posting with no marks left on the barrel.
Machined from a solid rod of Aluminum - the new Sentry is featuring a finish not used till now by Gravitas the Anodized - Bead Blasting, a unique texture that further refines the experience of using one of these writing instruments. Different from previous versions - the Sentry features two o-rings : - a black one that ensures the link in between the section and barrel is solid - a red one that ensures the cap's airtightness and prevents the cap from coming off when its not needed.
The 25mm-long section, tapering from 13.25mm to 11.5mm, is expertly crafted from Stainless steel alloy - PvD coated in black and features finely machined circular grooves for an enhanced grip. Machined from a single block of Aluminum the cap and the barrel are anodized in black color and a matte texture.
The Sentry is equipped with a Gravitas-produced size 6 steel nib, compatible* with Jowo No. 6 threads, and an ABS plastic feeder. It offers a range of nib options, including Extra Fine, Fine and Medium.  Each Sentry pen comes provided with a standard international plug-in cartridge converter.
