Copper drinkware is only suitable for water, not for example milk, citrus juices, and acidic liquids. Do not wash in the dishwasher. Clean with natural soap, a soft sponge, and room temperature water. Do not expose to direct sunlight. Our unique copper drinking bottles, jugs, water tanks, and cups have been handcrafted in India for centuries. Precisely because it is handmade, each item is unique and may differ slightly from the photo. There may also be irregularities in the material: this is part of the natural properties of copper.
