I usually go to the post office three times in the week. I use Japan post service that has excellent systems,it takes only 2 or 3 days to depart from japan. But usually it takes one week or more to U.S.A,and Europe.
I have sold many items on ebay,i didn't have any trouble with foreign customers. My ites are almost small,so I enter a small packet by airmail.It is cheeper but not insured. If you need a tracking number and an insurance,you need more charge. Please read my shipping detail. If you have any more question,feel free to ask! Have a nice shopping!! Thank you.
