Matchbox is a toy brand which was introduced by Lesney Products in 1953, and is now owned by Mattel, Inc, which purchased the brand in 1997. The brand was given its name because the original die-cast "Matchbox" toys were sold in boxes similar to those in which matches were sold. The brand grew to encompass a broad range of toys, including larger scale die-cast models, plastic model kits, slot car racing, and action figures.
