Kaweco Sport Prototype – Green Ebonite fountain pen

Kaweco Sport Prototype – Green Ebonite – Collectible Fountain Pen

The Kaweco Sport is widely regarded as one of the world's most iconic pocket fountain pens.
First introduced in 1911, it revolutionized compact fountain pen design with its famous motto: "Small in the pocket, great in the hand."

This remarkable example is a Kaweco prototype, believed to have been produced between 2000 and 2010.
Based on extensive research, it has been identified as a pre-production model, making it an exceptionally desirable piece for Kaweco collectors and enthusiasts.

The pen is crafted from green ebonite, one of the oldest and most prestigious materials used in fountain pen manufacturing.
Invented by Charles Goodyear, ebonite is produced by vulcanizing natural rubber with sulfur and was the very first material widely used for fountain pens. Warm to the touch, it develops a beautiful patina over time, enhancing its unique character.

Measuring only 10.5 cm when capped, the Kaweco Sport is easy to carry anywhere.
When the cap is posted, it extends to approximately 13 cm, providing a comfortable and well-balanced writing experience.

The pen is fitted with an original gold-plated stainless steel Kaweco nib in Medium (M), offering a smooth and enjoyable writing performance.
Its piston-filling mechanism, combined with its prototype status and green ebonite construction, makes this fountain pen a truly fascinating collector's item.
An exceptional opportunity to own a rare piece that represents a little-known chapter in Kaweco's history.
