OHTO Horizon GS01-G5 All-Metal Gel Pen 0.5mm G2 Refill Compatible Japan

OHTO Horizon GS01-G5 All-Metal Gel Pen — 0.5mm, G2 Universal Refill, Four Colourways, Japan

• One-Piece Aluminium Alloy Barrel — Machined, Not Assembled: The GS01-G5's barrel is machined from a single piece of aluminium alloy — no seams, no joints, no plastic inserts. The result is a pen that feels solid and balanced in the hand, with a weight and rigidity that plastic-barrelled pens cannot replicate. OHTO JAPAN is laser-engraved along the barrel, not printed.
• G2 Universal Refill Compatible — Use Any Brand: The GS01-G5 accepts any standard G2-format refill — Parker, Pilot, Uni-ball, Zebra, or OHTO's own gel refills — giving you complete freedom to choose your preferred ink type, colour, and line width without being locked into a proprietary cartridge. A future-proof pen body built to outlast its first refill by years.
• 0.5mm Needle Tip — Precision Line, Minimal Footprint: The stainless steel needle tip delivers a clean, consistent 0.5mm line with no spread or bleed — fine enough for tight annotation and margin notes, smooth enough for continuous writing. The needle tip also improves sightline to the writing point, making it easier to write precisely along ruled lines.
• Top-Button Click Mechanism — Smooth, Positive Action: The click mechanism is machined into the metal top button and engages with a clean, positive action — no rattle, no wobble, no plastic feel. The tip extends and retracts with the same satisfying precision as the barrel it sits in.
• Four Colourways — Gunmetal Grey, Silver, Crimson Red & Rose Gold: Each colourway is anodised directly into the aluminium — a surface treatment that is more durable than paint, more consistent than coating, and more resistant to chipping and fading over time. Four tones that cover the full range from understated professional to warm personal. Made in Japan.
