E-packet is for the some country may not have tracking show as send for china air mail
it is send faster then china air mail
but slower than EMS
it is provide by EMS company
I suggest that Canada and Germany that did not have tracking show of china air mail use this
if you use china air mail
it will not have tracking slow in English
and did not have tracking out of China
E-packet is about 10 to 15 days reach
