Our Copper Drinking Straws are not only eco-friendly but look uber trendy whether you're sipping a moscow mule or a smoothie. Straws are made from stainless steel, plated with pure copper then coated with a clear, food-safe lacquer externally to ensure the gleam is maintained. A cleaning brush is provided and more information on product care and cleaning can be found here. They make the perfect accompaniment to our beautiful copper mugs.
