Airmail takes between 1 and 2 weeks and costs about W244 000 to send a 30 kg box. *it is cheaper to send lighter things as the cost is measured by weight*
Surface mail, which is by ship, takes between 2& 3 months, and the biggest box you can send can hold a maximum of 20 kg's and costs about W50 000.
here is a picture of the biggest size box (max. weight allowance = 20kg's)
Farmboy and I have already shipped 2 boxes home, and will be sending another one soon. So we cannot say for sure that it is 100% reliable until the box arrives. But I have been assured by friends that it *will* get home!
Other than that, I have also sent 2 small packages home, each weighing about 1 kg.
I sent them airmail, which only cost W25 000 each. And they arrived safe and sound no problem in about 2 weeks.
Each time, I have been issued with a tracking number, and the people at the Post Office here in Korea have been super super helpful!
With sending bigger items, you have to buy the boxes from the Post Office (they are very cheap, the biggest costing W2 400, pictured above) and then once the have been filled, bring it back to the Post Office where they will tape it up for you : Cool hey.
Then there is a green form to fill in, which will be given to you by the Post Office... very easy and in English...fill in your address, the receivers address, a box to check what kind of stuff is in the box (merchandise, gift etc) , a place to write what's in it and give the value of each item.
