The lidded box is composed of a box and a lid hingably connected thereto. A bottom wall of the box is attached to the letter carrier's postal satchel. The hinge for the lid which is oriented more-or-less horizontally when the postal satchel is carried via its carrying strap in a normal manner, and is located at the lowermost location of the lidded box, whereby when the lid is opened, gravity naturally tends to continue swinging of the lid about the hinge until the lid depends downwardly therefrom and the lidded box is now open. A box wall extends from the bottom wall to a periphery, wherein the apex of each of the ridges of the cancellation ink stamp extend thereabove. The lid has a frictional fit and/or a snap fit with respect to the box wall. A touch tab is provided on the lid opposite the hinge to facilitate one handed opening of the lid.
