Wide range of materials from HOLZKERN

Natural materials like wood, stone or nacre have the great advantage of being naturally unique. Each wood is never like the other: depending on where a tree grew up and the climate it was exposed to, its wood differs not only in coloration, but also in grain and structure. The same is true for other raw materials, like marble, sodalite, slate or nacre: each piece has its own individual look.
So we can promise you that your Holzkern piece is 100% unique and there is no other in the world that looks exactly the same - just like your fingerprint or the color of your eyes.

The origin of the raw materials is, of course, also of utmost importance to us. For example, we work with tropical woods to be able to offer a great variety of colors. We care about the environment, so we mostly use FSC-certified wood. Where this is not possible, only residual wood from other industries, such as the furniture industry, is used - classic upcycling, in other words.

We’ve even been able to make many of our wood products completely waterproof thanks to our special Hydro-Defense technology. In this process, the wood is coated with transparent epoxy resin, so liquids simply roll off.
To ensure that our designs deliver what they promise, invisible metal reinforcements are sometimes built into the wood to maintain the classic Holzkern look. Some of our sunglasses even have carbon reinforcements to ensure the highest possible stability of the wood.
