Core Features

Walnut wood

Elegant & durable. The distinctive grain and the diverse range of colors from chocolate brown to almost black brown make this type of wood one of our favorites for the production of watches, jewelry, sunglasses and handbags. Walnut wood also impresses with its high density and the associated stability, which promises your piece of nature a long life!
