Cardboard box

Cardboard boxes are industrially prefabricated boxes, primarily used for packaging goods and materials. Specialists in industry seldom use the term cardboard because it does not denote a specific material. The term cardboard may refer to a variety of heavy paper-like materials, including card stock, corrugated fiberboard, or paperboard. The meaning of the term may depend on the locale, contents, construction, and personal choice. [Cardboard box. Wikipedia]
