OHTO GS02 Review: 0.5mm Gel Pen, Grip and Refills
Updated: Sep 21
The OHTO GS02 is worth considering if you want a refillable 0.5mm gel pen with a metal body and a fine needle-point tip. Its main trade-off is the firm grip: someone who prefers a soft, cushioned or very lightweight pen may prefer a different design.
Marukaku sells the products discussed in this guide. The recommendations below explain their features and intended uses; comfort and ink performance also depend on your grip, paper and writing style.
What makes the GS02 different?
The GS02 combines an aluminum barrel with brass components and a shaped grip. The metal construction is a central reason to choose it over a basic plastic pen. Marukaku lists Old Green and Matte Silver; check the product page for current color availability.
The 0.5mm needle-point tip leaves the writing area easy to see. That makes it a useful design to consider for small handwriting, annotations and detailed notes. A fine point does not guarantee the same line width on every paper.
Writing feel and grip
The ceramic-ball gel writing system is designed for smooth ink delivery. The grip is firm rather than cushioned, so choose it for the shape and material rather than expecting a soft rubber feel. Comfort during a long session is personal; a metal body alone does not make a pen more comfortable.
For planners, check drying and show-through on your own paper before writing across a full spread. Allow ink to dry before highlighting. No universal drying-time or bleed-through claim applies across all combinations of ink and paper.
Advantages and trade-offs
Reasons to choose it: a refillable format, a fine needle-point tip and a metal body in understated finishes. Reasons to consider something else: a preference for a cushioned grip, the lowest possible price or several ink colors in one pen.
Which refill fits the OHTO GS02?
OHTO specifies the Ceramic Roller Gel PG-M05NP refill for the GS02. It has a 0.5mm needle tip. Match this model when replacing the original refill; a shared tip size alone does not establish compatibility.
The Lite Touch is a ballpoint alternative to consider when a lightweight everyday pen matters more than metal construction. For several ink colors in one compact pen, look at the Uni-ball One 3 instead.
Who should choose the OHTO GS02?
Choose it when you specifically want a fine-point metal gel pen for notes, annotations or everyday writing. Choose an alternative when your main need is a soft grip, a lighter body or multiple colors. The best value comes from selecting the features you will actually use.
