Although it's still common for people to talk about making a 'carbon copy' of something, carbon paper is an unfamiliar concept to many of those who have grown up in the computer age.
A mainstay of offices of the past with their banks of manual typewriters, carbon paper enabled people to make duplicates of a document.
It was also used when making credit card payments, with the card details being copied onto the paper for the vendor to keep.
A succession of inventions, ranging from photocopiers to chip and PIN machines, has rendered carbon paper all but obsolete.
But there is one British firm still manufacturing carbon paper - York Haven in the West Midlands.
BBC News went to meet production director Mervyn Jones to find out how the company has remained in business.
