Airmail M-Bags  
Airmail M-Bags deliver a large amount of mail to a single addressee.
All categories of printed matter can be enclosed in an Airmail M-bag.

Printed matter is defined as paper on which words, letters, characters, figures, images, or any combination thereof, not having the character of a bill or statement of account, or of actual or personal correspondence, have been reproduced by any process other than handwriting or typewriting.

Maximum weight - 66 pounds (including the tare weight of the sack).
Identification - PS Tag 158, the Airmail M-Bag Addressee Tag, must be completed and attached to the neck of the sack.
Allowable Contents - Certain categories of merchandise can be combined with printed matter in an M-bag provided that all of the criteria are met for allowable contents.
