This medium nib, black Kaweco fountain pen features a 23ct gold-plated, steel nib and iridium tip. Kaweco have been successful in the writing market for decades, with the Kaweco Classic Sport their most popular pen. 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). The solid black resin and gold accents make this an eye catching addition to any writing set and it\'s small size means it can be carried with you at all times. The Classic Sport follows the original 1935 design and features the Kaweco logo in metal on the end of the cap. Kaweco fountain pens use international short ink cartridges. - Pen Size Closed: 105mm - Pen Size Open: 135mm - Brand: Kaweco - Pen Colour: Black - Nib Size: Medium - Country of Manufacture: Germany - Cardboard Display Box and Black Ink Cartridge included
