Using this tumbler is 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 a good temperature for a long time. When you fill it with hot water, be aware that the steam might lift the lid. That's okay and doesn't mean there's anything wrong with the product. To maintain it, you can wash it with mild dish soap and warm water. Don't use abrasive cleaners as they might scratch the surface. Also, dry it thoroughly after washing to prevent rust if there are any metal parts.
