We just received our stainless steel water bottles and we simply adore them. They are made from high quality #304 (18/8) food grade stainless steel, which is naturally safe. Non toxic paint is used on the custom designed graphics. Each 20 oz bottle also comes with a high quality carabineer. We are happy to be carrying these bottles because each one helps to eliminate waste! They are a safe and stylish way to have a cold beverage with you at all times.
