WoW! Double walled thermos cup with recycled stainless steel outer wall and PP inner wall. The cup has a black transparent push on lid with a sealable drinking opening. The bamboo bottom is a striking detail, with a thickness of 1. 5 cm. Certificated. Total recycled material: 38%. Capacity ml. Stainless steel can be recycled an infinite number of times whilst retaining the quality of the material. By using recycled stainless steel, fewer new raw materials are needed. This means less energy consumption, less use of water and a reduction of emissions. A responsible choice. Each item is supplied in an individual brown cardboard box.
