A lunch box is a container used to carry meals, typically for school or work. It is designed to keep food fresh and secure during transport. Lunch boxes come in various shapes, sizes, and materials, including plastic, metal, and insulated fabric. They often feature compartments to separate different food items and may include utensils or ice packs. Many people use lunch boxes to promote healthier eating habits by preparing meals at home instead of buying fast food. Popular among students, a lunch box can also be personalized with designs or characters, making it a fun accessory for children.
