This flask comes in a metal case, while its black, grippy, anodised coating makes it almost too sexy to use! Inside there is a copper coating to improve insulation. Performance was okay and you get clear instructions. But the plastic lining of the cup does not extend as far as some around the lip to prevent burns. The screw-top pourer was not easy to open with gloves. It’s a high price too.
