What is created by mass production custom made jewelry novels computers or paintings?

Mass production typically creates items that are manufactured in large quantities using standardized processes, such as computers and some types of jewelry. Custom-made jewelry and paintings, on the other hand, are unique creations tailored to individual preferences and not produced in bulk. Novels can be mass-produced in terms of printed copies, but each story is an original work. Therefore, mass production primarily applies to computers and certain types of jewelry.
