Natures finest: Well known as closure for wine, cork now gets a completely new way of application. Our Cork series is made of thin cork shavings from the bark of the cork oak tree. This process is done only every ten years and cork renews itself naturally, so the stripping doesn’t harm the tree at all. Much of the production is hand crafted in Portugal. Cork is not only organic, but also naturally water-resistant, sustainable, fire resistant and long lasting. For additional sturdiness we laminated a rigid cotton canvas material to it.
