"Material: Stainless steel and silicone"; "double-wall vacuum insulated keeps drinks cold for up to 10 hours"; "The silicone sipper spout has a built-in valve that stops water from flowing when no one is drinking"; "Recommended for kids aged 3+". FAQ: "Hand washing the cup is recommended to preserve its bright design"; "avoid using straw brushes as they can damage the built-in valve"; "these cups are designed for cold or room-temperature beverages only" and are not safe for the microwave; "a small amount may leak if a heavily filled cup is left lying on its side for an extended period." The page names no steel grade, no lid or ring material, no coating, and makes no BPA, lead or phthalate statement and no testing statement.
