WoW! Double-walled, leak proof thermos cup made from recycled stainless steel. Finished with a matte finish. With PP screw lid, click opening and non-slip bottom. Not dishwasher-safe. RCS-certified. Total recycled material: 77%. Capacity 450 ml measured to the rim, without lid. Capacity measured with lid approx. 300 ml.Stainless steel can be recycled many times whilst retaining the quality of the material. By using recycled stainless steel, fewer new raw materials are needed. This means less energy consumption and less use of water.
