Seven components – that's how many individual parts make up the Kaweco Sport fountain pen, made of high-quality plastic. Unlike fully automated machinery, these writing instruments are usually assembled by hand every day in our factory in Nuremberg. This time, you get to do it here at Papillon Press!

Slip into Kaweco's shoes and build your own personalized fountain pen with the Kaweco DIY Sport. This pen is available exclusively for assembly and pickup in brick-and-mortar stores as a DIY product and is not currently available to ship.

Glow in the Dark is the color of the year for 2026.

In 1911, something special was created: the Kaweco Sport. The pocket fountain pen measures just 10.5 cm when closed, making it the perfect travel companion. With the cap repositioned, it expands to a regular size of 13 cm.
