uni-ball one P 0.5mm - Grape

Bring a sense of calm, executive sophistication to your everyday carry with the uni-ball one P 0.5mm - Grape (Product Code: UMNSP05.63). Another celebrated star in this award-winning Japanese stationery collection, the "P" model (short for Pocket) challenges traditional long pen design by introducing a short, beautifully chunky, and ergonomic body. It is engineered specifically to give you a "fine feel that fits naturally in your hands."

Dressed in a dusty, muted pastel purple Grape barrel, this 0.5mm edition is paired with a gleaming, high-shine silver metal wire clip and an internal metal stabilizer tip. It is the ultimate piece of pocket-friendly writing perfection designed to anchor your evening journals, workspace notes, and daily scheduling.

Key Features

• Delightful "Chubby Pocket" Silhouette: Measuring a compact 4.6 inches (116.8 mm) long, its short and broader layout rests comfortably inside the hand while slipping effortlessly into small pocket organizers or planner loops.
• Advanced Low Center of Gravity: Houses an internal brass stabilizer mechanism tucked behind the tip. This heavy nose piece secures the refill to eliminate micro-wiggles and biases the pen's weight forward for incredibly stable, fluid lines with less writing pressure.
• Guinness Record-Breaking BEADS-PACK Ink: Pre-filled with an intensely rich black gel ink. The unique pigment particles are engineered to lock cleanly on top of the paper fibers rather than sinking or bleeding into them, making your script stand out in a beautifully crisp, vivid way.
• 0.5mm Smooth Conical Tip: The medium-fine 0.5mm configuration provides a buttery-smooth ink flow that keeps lines sharp, punchy, and highly legible across all paper qualities.
• Rapid-Drying & Bleed-Resistant: Features an optimized solid-to-liquid ratio that allows the liquid carrier to absorb instantly while the black pigment binds to the surface, delivering flawless, smudge-free performance.
• Wide-Opening Stainless Steel Clip: Features uni-ball's signature spring-loaded wire pocket clip, built wide and tactile like a heavy-duty clamp to latch securely onto thick journal covers, leather folders, or clothing pockets.
