Only printed matter is admissible in M-bags. Articles that meet the definition of “printed matter” include newspapers, magazines, journals, books, sheet music, catalogs, directories, commercial advertising, and promotional matter. “Printed matter” is defined as follows:
- Papers upon which words, letters, characters, figures, images, or any combinations thereof appear.
- Papers that do not have the character of a bill or statement of account.
- Papers that do not have the character of current and personal correspondence.
