Storage boxes are containers used to store items and can come in a variety of shapes and sizes. The term 'storage box' can refer to two different solutions found in a crossword puzzle: BIN (3 letters) and CEDARCHEST (10 letters). A BIN is a small, open-topped container typically used for storing small items. A cedarchest is a larger, wooden storage box with a hinged lid that is often lined with cedar wood, which helps protect stored items from pests and moisture.
