A Striking Glow-in-the-Dark Design

The standout feature of this special edition is its translucent green body that glows brilliantly after being charged with natural daylight or UV light. Whether stored in your pencil case, carried in your bag, or used for late-night journaling under the covers, the luminous finish creates a captivating visual effect that sets it apart from traditional fountain pens.

Finished with elegant silver-coloured accents, the Glow in the Dark edition perfectly balances playful innovation with the timeless design language of the Kaweco Sport collection.

The Iconic Kaweco Sport Design

Originally introduced in 1911, the Kaweco Sport remains one of the most recognizable pocket fountain pens in the world. Compact and portable, it measures just 10.5 cm when closed, making it easy to carry wherever you go.

When the cap is posted, the pen extends to a comfortable writing length, providing the perfect balance for extended writing sessions while maintaining its pocket-friendly portability.

For most writers, Kaweco recommends the versatile Medium nib, which offers an excellent balance between smoothness and precision.

All nibs are manufactured in Germany and engineered to provide reliable performance and an enjoyable writing experience.
