GS01 Roller Gel Pen 0.5mm / OHTO

The GS01 is a full-metal gel pen with an aluminum body that shifts from hexagonal to round along its length, giving you a firm grip where you need it and a clean silhouette where you don't. The needle tip keeps your sightline clear while writing, and the refill uses the widely adopted G2 standard, so replacements are easy to find.
