Handmade from 100% Certified Copper, slim and easy to hold 34 oz. Pure copper develops a bluish-green patina, so don't be alarmed by this color. However, copper can react with substances in some drinks, particularly acidic ones, so it's recommended only to store water. When cleaning, add 1/4 cup of vinegar and 1 tbsp of salt to warm water, shake vigorously, and pour it out. Rinse thoroughly with plenty of fresh water.
