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 CO2 emissions. A responsible choice. Each item is supplied in an individual brown cardboard box. This product can also be personalized with custom engravings or logos for a truly unique touch.
