Kaweco Classic Sport Fountain Pen - Black
The Kaweco Classic Sport series is based on an octagonal design with an oversized cap, and was first used by Kaweco in the 1930s. The fountain pen is just 105mm when closed, however when the cap is posted on the barrel it becomes a full sized 135mm fountain pen - hence the slogan "Small in the pocket, large in the hand".
The pen is made of plastic, and the gold Kaweco logo is on top of the cap. The Classic Sport's gold nib is made by Bock of Heidelberg and is available in 5 sizes from extra fine to extra broad.
