No Proper Closing of the Arzum Duoterm Thermos Lid
I purchased the Arzum Duoterm thermos with two containers in red, model AR 722, with a capacity of 1.5 liters. I've used... it 5-10 times, and the lid of the inner container won't close. I want to replace the lid. I've reached out to all possible places where I could find official service information,
