Went to the post office today to get a quote to send a marker abroad and they told me they cant do it on any service because its a prohibited item, also tried a couple of couriers and they all said the same thing. so i wondered how people send theirs? do you guys just risk it? having the innocent mind of a child i saw royal mail x-raying most packages sent for air / international mail and would probably catch most items? am i vastly over estimating their screening process?
