Ystudio Rollerball Pen
Built to last a lifetime, this rollerball pen features a brass barrel and cap that is hexagonally shaped with rounded edges. It's heavy enough to provide a stable grip, and balanced enough for a smooth writing experience and will oxidize over time — giving you the option to showcase its individual character or polish with bronze oil to resurrect its original shine.
