A lunch box is a portable container designed to carry food for consumption later in the day, available in various materials like plastic, metal, or fabric. Typically featuring a main compartment with dividers or smaller containers for organization, it often includes additional compartments for utensils or drinks. Used by people of all ages, from schoolchildren to professionals, lunch boxes offer a convenient and eco-friendly way to transport homemade meals, reducing reliance on disposable packaging and enabling individuals to enjoy their food on the go.
