What is a freezer mug?

A freezer mug is a type of cup or mug that is designed to keep beverages cold for an extended period of time. It is typically made from a material such as stainless steel, plastic, or ceramic, and has a double-wall construction with an insulating layer in between. This helps to prevent heat from transferring from the outside of the mug to the inside, keeping your drink cold for longer. Some freezer mugs also have a gel lining inside the mug that can be frozen, further extending the cooling effect.

Freezer mugs are a popular choice for people who want to enjoy cold beverages on hot days, or who simply want to keep their drinks cold for a longer period of time. They are also popular for use in commercial settings, such as restaurants and bars, where it is important to keep beverages cold and well-chilled.
