Card board box Hanoi

In Hanoi. Need to send items home by mail.

Where can I find shops that sell card board boxes?

The post office will supply you with one. Cheap. You can't seal anything before it passes customs anyhow so you might as well just take it there. They have all the tape and magic markers too. You have to fill in a customs form - 20,000 dong ???

Take a book- there are sometimes line ups and it's slow.
