We recommend transferring water to a glass or stainless steel container before adding citrus or other ingredients. Not suitable for use with acidic, carbonated, or flavored beverages. Please note: Pure copper is a soft metal and may develop surface marks or dents with regular use. Over time, natural oxidation may occur—this is a normal characteristic of pure copper and can be managed with regular cleaning. Each bottle is individually inspected before shipment. To enhance the sealing performance, we've recently upgraded the gasket material and now include an extra replacement gasket with every bottle.
