Storage compartments are containers used to store items. They come in a variety of shapes and sizes, and can be made from a variety of materials. The two most common types of storage compartments are BAYS and bins. BAYS are typically larger and more open than bins, and are often used to store large items such as furniture or appliances. Bins, on the other hand, are smaller and more enclosed, and are often used to store smaller items such as clothing or toys.
