The Kaweco Sport fountain pen has been a customer and staff favourite for a long time and for good reason. Featuring a classic octagonal design that goes back to the 1930s, the Sport's pocket sized design allows it to be ultra portable, but with the comfort of a full size pen once the cap is posted (which takes the fountain pen from 105mm to 133mm in length). Kaweco include one international size ink cartridge with the Sport, and you can order a variety of replacements from the brands we stock. The Kaweco Sport's nib is a 23ct gold plated steel nib, which wrote smoothly in all nib sizes we tested. We would recommend starting with a medium or fine nib. If you like to secure your pen with a clip, pick up one of Kaweco's optional octagonal pen clips (available in gold to match the Sport's nib and trim, or alternatively silver).
