Tin box

A tin box was a box used for storage of objects or food.

Behind the scenes
The Dalek Tin was a part of a BBC VHS release in September 1993. It contained copies of The Chase and Remembrance of the Daleks, a booklet, Daleks: A Brief History by Andrew Pixley and one of five possible Dalek photos on the bottom. The US release featured no book or tin, with both stories packaged in one box without individual artwork.
