T3 is a series of robust vacuum flasks, available in different sizes and colours. For higher efficiency, the inside of the flask is equipped with a dual insulation made of silicone and steel-free material. Polypropylene, which is used in this product, has the advantage of being not only non-breakable, but also especially hygienic. With its round contours, the mug is reminiscent of a cup, allowing users to enjoy hot drinks. All parts can easily be disassembled for cleaning and easily be reassembled afterwards.
