Ohto Horizon GS01-G5 Rollerball Pen / Silver

This reimagined OHTO GS01 features their signature flash dry gel ink and longer needle tip. It delivers smooth, precise writing with a clear view of the writing point for greater control. The redesigned clip, which is made of brass and wraps around the top of the pen, is another notable change from the OHTO GS01. Crafted from aluminum, the barrel transitions seamlessly from a hexagonal grip to a round body, providing a comfortable, secure hold while giving the pen a sleek, refined look. Its full-metal construction adds a satisfying weight and premium feel, making it an ideal choice for both everyday writing and detailed note-taking.
