These stamps are a waist of government money due to most of them are never used or get damaged by the humidity or temperature in our government office that in our case are many times inside of a freezer or cold warehouse. In top of that the USA Post Office personal many times do not even recognized or accept this kinds of stamps as officila due to their lack of training in this respect. I have received mail back returned because the stamp felt out or got dettached from its envelope. I would suggest another alternative method to officially stamp our mail, like an ink pad rubber stamp.
