YSTUDIO writing instruments are defined by two timeless features: solid brass barrels that develop a unique patina over time, and a hexagonal form inspired by the pencil—evoking the feeling of picking up a pen for the first time.
Our most popular designs include the Classic Fountain Pen, Classic Rollerball Pen, and Revolve Ballpoint Pen, each crafted for everyday writing with lasting character.
