In more modern times the selection box as we know it has become a staple Christmas gift of chocolate.
Each chocolate company produces these at Christmas time and they are often filling the spaces near supermarket checkouts.
Children expectantly received a selection box each year and regarded them as a main Christmas gift.
Hand picking is expensive, but early automated systems lacked flexibility; the layout or contents of a box could not be changed without making alterations to the machinery.
