Box-in-box

**Box:** A box is a rigid container used for storage, transportation, or display of its contents. Typically featuring flat, often rectangular, sides, boxes range in size from very small containers, like matchboxes, to large shipping containers for furniture. Boxes serve diverse purposes, from purely functional to decorative, and form a ubiquitous part of packaging and storage solutions.

Boxes are manufactured from a wide array of materials, selected based on the intended use and required durability. Common materials include durable options like wood and metal, and less durable options such as corrugated fiberboard and paperboard. Closure mechanisms vary, employing flaps, doors, or separate lids, and can be secured with adhesives, tapes, strings, or more sophisticated clasps, catches, or locks. The specific design and construction of a box is often tailored to the product it is intended to contain.

Numerous specialized types of boxes exist for specific purposes. In packaging, these include corrugated boxes for shipping, folding cartons for retail goods, and rigid setup boxes for protecting high-value items. Storage applications include jewelry boxes, hat boxes, toolboxes, and strongboxes for valuables. The term "box" is sometimes used interchangeably with "carton," depending on the context and region. Large steel intermodal shipping containers have significantly impacted global commerce.
