A tiffin is a type of lunchbox commonly used in India and other South Asian countries to carry meals. It typically consists of multiple stacked containers that hold different dishes, allowing for a variety of foods to be packed and consumed. Tiffins are often made of stainless steel and are popular for their practicality and ability to keep food warm. They are widely used by students, workers, and families for convenient, home-cooked meals on the go.
