The Classic Sport closely follows an original 1935 octagonal design 'Small in the pocket, large in the hand'. The oversized cap arrangement creates a small closed pen but a full length open pen. Closed, the pen is just 105mm long, open 133mm long. The barrel is 14mm in diameter (around the cap). Made from tough but exceptionally lightweight ABS macrolon plastic. Features the Kaweco logo in metal on the end of the cap.
