Keep your favorite hot beverages at the perfect temperature. Use along with your favorite mug at home, in school or at work. Set any non-plastic mug or non-paper cup on the warmer and never worry about your coffee, tea, hot cocoa or soup going cold before you drink it Plug the warmer in, set it on your desk or counter, put your mug or cup on it and go about your busy day, knowing your beverage will still be warm when you're ready to drink it. Note: While this warmer never reaches a temperature that is hot enough to cook your beverages, for safety reasons, please keep the warmer on a flat surface that is free of clutter and never leave it on unattended or for long periods.
