Its tapered shape lends this vacuum mug the appearance of a decanter, allowing it to be held securely. The double-walled insulating core keeps beverages hot or cold for hours while the inner container, made of stainless steel, is dishwasherproof. The all-round opening is triggered by pressing a button and enables drinking straight from the mug and pouring without spilling out of any part of the lid. The large plastic screw cap is completely tight, even upside down and is easy to dismantle for cleaning.
