I purchased this in a DEAN & DELUCA lucky bag a few years ago. It has a screw-top cap with a high degree of airtightness, making it easy to carry around. It also has a vacuum-insulated double-wall structure, providing excellent heat and cold retention. I've only used it a few times, so I think there are no noticeable scratches or stains overall. Please refrain from purchasing if you are sensitive to used items, as it has been stored and inspected by an amateur.
