Maintenance method: Avoid collision and impact in the process of using the thermos cup, in order to avoid damaging the cup body or plastic, causing thermal insulation failure or water leakage. When tightening the cup lid, the force should be appropriate, and do not rotate too much to avoid the failure of the screw buckle. When drinking coffee, tea or beverage frequently, the inner container will change color. This is a normal phenomenon.
