These goods can be broken very easily , so we would be thankful if you would be sure to use durable packing materials .   That will be no problem . We never use any kind of inferior packaging . Your goods will be safe .   Good . Can we ask you to put a country of origin mark on each container ?   We always do that , but I will make a point to check it for you since it is so important .   Do you always put a quality mark on each container ? For this shipment it is crucial to us that you do .   We don't usually do that unless we are asked to . I'lI tell my staff to take care of this for you .   Thanks . This shipment is so important to us there cannot be any foul-ups .
