Have you seen a cardboard box?

In the United States, the jewel box of a music CD was originally packaged for retail sale in a large cardboard box called a longbox in order to fit in store fixtures designed for vinyl records, offer larger space for display of artwork and marketing blurbs, and deter theft. This packaging was much-criticized as environmentally wasteful, and was eventually dropped. However, the Beatles' "Capitol Albums" series features longbox packaging, although a shorter, fatter box called the "brick" is also available.
