Kinto Insulated Travel Tumbler 500 ml The Kinto Travel Tumbler is designed for people who lead a conscious and flexible lifestyle—for those who appreciate the subtle flavours of single origin coffee and tea, or like to drink mineral water at the temperature that is just right for your body. The vacuum insulated tumbler has great heat and cold retention, and maintains the aroma and flavour of drinks for a long time. - The cap is simple without excess details and you can drink from any angle pleasantly, like drinking out of a glass or mug. A special structure catches ice cubes and drinks come out in perfect amount. - Double walled stainless steel tumbler prevents heat transfer with a vacuum between its inner and outer walls. The foil layer covering the inner wall reflects heat back inside, contributing to excellent heat and cold retention. - In addition to usability, material and texture support long-term use. Made of durable 18-8 stainless steel, the tumbler does not rust easily. The coloured tumblers have a powder coat finish on the surface which prevents scratches. - High quality stainless steel helps to preserve the rich aroma and flavor of drinks. The smooth electro-polished interior prevents odours and stains, letting you maintain it clean and fresh.
