The stainless steel and copper components of the OUVER Coffee products are composed of the materials of selected companies that store their left-overs in containers and then clear it for recycling. We search these containers for any usable left-over materials. In this way, we revitalize them even before the recycling process begins. The quality, however, shall not suffer because of this. Since the materials aren’t exactly disposed into the containers with a lot of care, the components of OUVER products may show light scratches. This is part of the charm of each product and makes it unique!
