Using this tumbler is super easy. Just open the lid and pour in your favorite drink, whether it's hot coffee or cold juice. The tumbler will keep it at the right temperature for hours. When it comes to cleaning, you can simply wash it with mild soap and water. As a reminder, when you fill it with hot water, be aware that the steam may cause the lid to lift. Don't mistake this for a quality problem. To maintain its performance, avoid using abrasive cleaners that could scratch the surface. Also, make sure to dry it thoroughly after washing to prevent rusting.
