Klassic 40 Dark Blue Acrylic

Klassic 40 marks the 40th Anniversary of Kanwrite, established in 1986.

Crafted for writers who value timeless design, precision engineering, and refined materials, the Kanwrite Klassic 40 is a CNC-machined fountain pen made from premium acrylic resin. Inspired by the classic cigar-shaped fountain pen design, its gently curved silhouette and refined proportions create a timeless aesthetic while offering a substantial, well-balanced feel in hand.

Designed for exceptional writing comfort, the Klassic 40 features an ergonomically shaped hourglass grip section that naturally follows the contours of the fingers. This comfortable profile provides a secure, relaxed grip and makes the pen especially well-suited for extended writing sessions.

The Klassic 40 offers a choice of two feeder options to suit different writing preferences. The ebonite feeder delivers a generous, wet ink flow—ideal for writers who enjoy a rich and expressive writing experience and is highly recommended for flex and broader-tipped nibs. The ABS plastic feeder provides a more controlled, regular ink flow for dependable everyday writing and is recommended with Medium or finer nib sizes, including F and EF.

With 7 stock nib options, the Klassic 40 gives writers the freedom to choose a writing experience that matches their style—from precise everyday writing to broader and more expressive strokes. Combined with Kanwrite’s versatile 3-in-1 ink filling system, the pen supports cartridges, a converter, and eyedropper filling, offering flexibility for every kind of writer.

Precision-machined from premium acrylic resin, thoughtfully shaped for comfort, and inspired by the enduring cigar-shaped fountain pen form, the Kanwrite Klassic 40 is a modern classic created to celebrate 40 years of Kanwrite and the timeless joy of writing with a fountain pen.
