750 ml with a screw top. ECO-FRIENDLY ALUMINUM WATER BOTTLE 86% of plastic water bottles used in the U.S. end up in landfills, taking up to 1000 years to biodegrade. Consumers are embracing the trend to reduce this number by using aluminum water bottles. Each 750ml bottle is extrusion-pressed from a single piece of aluminum for seamless, leak proof construction. Recyclable.
