A breadbox (chiefly American) or a bread bin (chiefly British) is a container for storing bread and other baked goods to keep them fresh. They were a more common household kitchen item until bread started being made commercially with food preservatives and wrapped in plastic. Breadboxes are still used by many people to store commercially purchased bread, but are used more especially by people who bake bread at home. Newer ones are usually made of metal. In the past they were often made of wood or sometimes pottery (pottery breadboxes are also called bread crocks). Old breadboxes can be collectible antiques.
Breadboxes are most commonly big enough to fit one or two average size loaves of bread—about 12 inches wide by 6 inches high and deep (30 cm x 15 cm x 15 cm).
