A travel mug is a portable container designed to hold beverages, typically coffee or tea, while on the go. It is usually made from stainless steel or plastic and features insulation to keep drinks hot or cold for extended periods. Many travel mugs come with a secure lid to prevent spills and a handle for easy carrying. These mugs are popular among commuters and outdoor enthusiasts, as they allow users to enjoy their favorite drinks without the risk of spills. Some travel mugs are also designed to fit in car cup holders, making them convenient for use during road trips or daily commutes.
