In this episode of Appelboom Bites, Joost Appelboom and co-host Clare Coco sit down with a true legend of the fountain pen world: Michael Gutberlet, CEO of Kaweco, now fondly known as the OBG – Old But Gold. We dive into Kaweco’s latest innovations, including the ingenious Mini Foldable Converter and the hugely successful Piston Sport—with exciting news from Michael about more colors joining the lineup soon!

Michael also gave us a sneak peek at a one-of-a-kind Liliput fountain pen made from a mystery “Rainbow” material currently in testing, and we discussed Kaweco’s strong presence at the Dutch Pen Show, especially the beloved DIY Kaweco Sport station.

As a special treat, Joost revealed the Kaweco Dutch Pen Show Waterworld 2025 Special Edition—a stunning collector’s piece featuring exclusive sleeve artwork by the talented Anne Nossack.

Plus, we had a blast with the amazing energy and questions from our YouTube Live Chat audience, who helped make this episode even more fun and interactive.
