To Go Click is the perfect travel mug for your favorite drink on the way to the office, school, or during a walk. The cup features a state-of-the-art smart click lid that allows you to open and close it easily with a push on the top. When closed, it keeps your coffee or tea warm for up to four hours or cold for eight hours. The 0.4-liter cup is made of steel, double-walled, and vacuum insulated for thermal efficiency. You can drink from the full 360 degrees of the cup as if there were no lid. Think of the environment and bring your own reusable coffee or tea mug when you are on the go.
