It is the close connection to nature that makes the colour green so pleasant. The dark green of the Classic Sport series is often found in Kaweco models from the past, making the fountain pen look especially nostalgic.
In 1911 something remarkable by the name of Kaweco Sport was created. The pocket fountain pen only measures 10.5 cm when closed. Therefore, it can easily be taken anywhere. With the cap mounted, it grows to a normal size of 13 cm.
