Classic design made of high-quality plastic combined with the latest technology: gel refill and ceramic ball.

The Kaweco Sport was born in 1911. The pocket roller ball pen only measures 10.5 cm when closed, and it grows to a normal size of 13 cm when the cap is mounted.

The invention of the roller ball made writing particularly easy and fluid. The gel flows uninterruptedly over the ceramic ball onto the paper surface. We are especially proud of the exceptionally soft writing feel of our roller ball system.

Mysterious as the moon

Houston, we have a new series: our new LUNAR SPORT takes a giant leap into our Kaweco standard range, shining in two stunning hues. While the colour Light Green has a softer shimmer to it, just like moonlight itself, our Shadow Green is more reminiscent of cool spring nights and blooming flower buds. Green and bronze hues go hand in hand with each other via a fascinating colour-changing iridescent pearl effect, depending on how the light meets the pen, leaving room for fascinating contrasts.

A play of light and shadow

The series two color variants embody a literal play of light and shadow. The dark base colour of our Shadow Green lets the colour effects pop, while one can see a more subtle display with Light Green. Opposites that enhance each other.

The light ABS material makes the pen feel almost weightless, making it effortless to write for long durations. Of course the Lunar roller ball is still as robust as all our famous Sport models despite this.

Shining companion

Our pocket-sized Kaweco Lunar Sport roller ball, weighing just 10.5 g, only measures 10.5 cm when closed. With the cap attached, it extends to a more standard size of 13 cm.

To complete the look, the pen is placed within our standard black paperbox. For further customisation, we offer blue and black high-quality refills with a 0.7 mm line width and clips in gold, silver, bronze, and black. To protect the pen, you can choose between a wide variety of pouches for Sport pens.
