I wanted a new fountain pen that would better fit my passport-sized Midori Traveller notebook. I’ve been using a Pilot Metropolitan and a Platinum Preppy. The Metropolitan is a little too fat. The Platinum fits better, but the clear plastic dresses down the Traveller. The Kaweco Classic Sport is a short, pocketable fountain pen that has a barrel that looked like it might fit inside the Midori pen loop without a clip (the Sport doesn’t come with a clip). The pen writes great. The fit in the notebook is okay, but not perfect. You can see how lose it is in the photo below. With a little help with the elastic band, it’s okay. I got the plastic version of the Sport, so I don’t worry about losing it as much as much as I would with a nicer pen.
