The great majority of bunkobon are A6 (105×148mm or 4.1"×5.8") in size. They are sometimes illustrated and like other Japanese paperbacks usually have a dust wrapper over a plain cover. Modern bunkobon can include bestsellers and works of scholarship alike and their pocketbook size make them useful while commuting. They are used for similar purposes as Western mass market paperbacks: generally for cheaper editions of books which have already been published as hardbacks. However, they are typically printed on durable paper and durably bound, and some works are initially published in bunkobon format.
