Box (plural boxes) describes a variety of containers and receptacles for permanent use as storage, or for temporary use often for transporting contents. The word derives from the Greek πύξος (puxos), "box, boxwood".

Boxes may be made of durable materials such as wood or metal, or of corrugated fiberboard, paperboard, or other non-durable materials. The size may vary from very small (e.g., a matchbox) to the size of a large appliance. A corrugated box is a very common shipping container. When no specific shape is described, a box of rectangular cross-section with all sides flat may be expected, but a box may have a horizontal cross section that is square, elongated, round or oval; sloped or domed top surfaces, or non-vertical sides.

A decorative or storage box may be opened by raising, pulling, sliding or removing the lid, which may be hinged and/or fastened by a catch, clasp, or lock.

Several types of boxes are used in packaging and storage.

Depending on locale and specific usage, the terms carton and box are sometimes used interchangeably.

Malvina Reynolds (August 23, 1900 – March 17, 1978) was an American folk/blues singer-songwriter and political activist, best known for her song-writing, particularly the songs "Little Boxes" and "Morningtown Ride".

Malvina Milder was born in San Francisco to David and Abagail Milder, Jewish and socialist immigrants, who opposed involvement in World War I.

She married William ("Bud") Reynolds, a carpenter and labor organizer, in 1934. They had one child, Nancy Reynolds Schimmel (a songwriter and performer in her own right), in 1935. She had earned her Bachelor of Arts and Master of Arts in English from the University of California, Berkeley, and later earned a doctorate there, finishing her dissertation in 1938.

Though she played violin in a dance band in her twenties, she began her songwriting career late in life. She was in her late 40s when she met Earl Robinson, Pete Seeger, and other folk singers and songwriters. She returned to school at UC Berkeley, where she studied music theory. She went on to write several popular songs, including "Little Boxes," "What Have They Done to the Rain," recorded by The Searchers and Joan Baez (about nuclear fallout), "It Isn't Nice" (a civil rights anthem), "Turn Around" (about children growing up, later sung by Harry Belafonte), and "There's a Bottom Below" (about depression). Reynolds was also a noted composer of children's songs, including "Magic Penny" and "Morningtown Ride," a top five UK single (December 1966) recorded by The Seekers.
