Thermal cups are specially designed containers that help keep beverages hot or cold for extended periods. They are often made from materials like stainless steel or double-walled plastic, which provide insulation. This insulation minimizes heat transfer, allowing drinks to maintain their temperature longer than regular cups. Many thermal cups come with secure lids and straws, making them convenient for travel. They are popular for enjoying coffee, tea, or cold drinks, especially for people on the go. Brands like Contigo and Thermos are well-known for producing high-quality thermal cups that cater to various needs and preferences.
