Abstract: A flexible mail carrying device, designed to be carried on the inner forearm between the elbow and hand, which will accommodate a mixed bundle of letter sized and magazine sized mail, as required by the U.S. Postal Service's one-bundle delivery method. The mail carrier includes a firm flexible base unit defining a rectangular back portion, with curved flaps at the full left side and full bottom side, and a movable, rigid, transparent retaining strap for securing the mail bundle. An absorbent washable cover attaches to the outer side of the carrier and can be removed for laundering as desired. The carrier can be used to safely and securely carry mixed bundles of mail, protects the mail pieces from undue body contact and offers a comfortable and hygienic means for a mail carrier to deliver a one-bundle system.
