I have designed my new beautiful boxes myself, which have been created to fit my earrings perfectly. The boxes are made from material that is FSC certified. This means that the trees from which the cardboard is made come from a forest where the forest owner must comply with a number of principles and requirements. These are requirements such as maintenance, where the forest owner must preserve and/or restore ecosystem services and environmental values. The forest owner must also avoid, restore or mitigate negative environmental impacts.
