A bag, also known regionally as a sack, is a common tool in the form of a floppy container, typically made of cloth, leather, bamboo, paper, or plastic. The use of bags predates recorded history, with the earliest bags being lengths of animal skin, cotton, or woven plant fibers, folded up at the edges and secured in that shape with strings of the same material. Bags can be used to carry items such as personal belongings, groceries, tools, and other objects. They come in various shapes and sizes, often equipped with handles or straps for easier carrying.
Bags have been fundamental for the development of human civilization, as they allow people to easily collect and carry loose materials, such as berries or food grains, while also allowing them to carry more items in their hands.
