WP Finewriter Black

Premium Japanese Writing Instrument Designed for Expression

The WP Fine Writer is part of Kokuyo's prestigious WP series — a collection of high-quality pens meticulously designed with the feel of writing at the forefront. This isn't just a pen; it's a writing instrument that makes you want to write more, letting you fully immerse yourself in the creative process. With the WP Fine Writer's exceptional smoothness, new ideas can emerge naturally, and you can freely express yourself on paper without interruption.

Innovative Resin Tip Technology

The heart of the Fine Writer lies in its specially engineered plastic tip. Unlike conventional pens, this resin tip features microscopic internal slits through which ink flows via capillary action, delivering ink directly onto the paper. This innovative ink discharge system creates an extraordinarily light and effortless writing experience — your pen glides across the page, helping you bring what's in your mind onto paper without any resistance.

The result? A smooth, uninterrupted flow that supports your thought process and helps organize your ideas as they emerge.

Expressive Bullet-Shaped Tip with Dynamic Flex

The Fine Writer's distinctive bullet-shaped tip is precision-designed to maximize the resin's natural flexibility, dramatically broadening your range of expression.

Variable Line Width: Because the tip flexes slightly with your writing pressure, subtle differences in how you hold and press the pen create beautiful variations in line thickness and stroke dynamics. This allows your characters, shapes, and illustrations to be expressed with rich emotion and personality.

From Sharp to Smooth: Create everything from precise stops to gentle, flowing curves. Add dimensional depth to your illustrations by varying line weight to highlight design choices or emphasize key points. Write each character carefully with expressive strokes that reflect your intention.

Versatile Writing Angle

Thanks to its unique tip design, the Fine Writer writes smoothly even when held at a low angle. This versatility means you can vary your grip depending on what you're writing — whether it's detailed notes, creative sketches, thoughtful journaling, or careful lettering.
