This is a vacuum-insulated bottle collaboration between NEIGHBORHOOD and REVOMAX. It's the SLIM 12oz (355ml) size and features a one-touch open/close cap. It has excellent functionality, keeping drinks hot for 18 hours and cold for 36 hours. Although it is unused, it has been opened, and the box has some scratches. Please purchase only if you understand that it has been stored at home.
