The Kaweco Collection takes favourite fountain pens and gives them a finish and trim uncommon for the range. In this case, the Mellow Blue takes inspiration from the blue summer sky and comes with a stainless steel nib. 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. Uses short international standard cartridges. The pocket clip is an optional item, available in various finishes to complement your Sport pen. Presented in a light blue card gift-box. In harmony with the blue sky in summertime, the Kaweco icon made of high-quality plastic is dressed in a touch of pastel blue. When closed, the pocket fountain pen is only 10.5 cm in size, making it the perfect companion for on the go. With the cap on, a normal size of 13 cm.
