Onyx Mechanical Pen



Inventery’s Onyx Mechanical Pen demonstrates the brand’s uncompromising commitment to quality. A modern, minimal take on a traditional writing implement, it’s been precision machined from a single brass rod to achieve a smooth, unibody finish. The sleek onyx black pen also features an all-brass click mechanism from Schmidt that guarantees a smooth and silent click in comparison to its adversaries. Each Inventery pen is completely unique, marked with an individual serial number.
