Sustainable wood

Trobla, suitably meaning horn in the Slovenian language, was created in a wood workshop by our dear Slovenian friends. Trobla consists of certified, sustainable wood, and comes in walnut and maple. We care as much about our planet as you do. That is why we made sure Trobla is fully recyclable and not dependent on batteries or electricity.

Trobla will bring a pleasant ambiance to every environment.

About the brand
Trobla was created in a studio by three of our dear friends from Koper, Slovenia. Even though they all have their own talents, they all share the same approach: "We wanted to start working with our hands, preferably using wood to create something completely new." Each one is handmade from sustainable and locally sourced wood. Did you know Trobla is the Slovenian word for horn!?
