I want a box like that

Where can I find a box like that?!
All I seem to find is tattered old scrappy parts of cardboard.
I'm starting in Stavanger, Norway, and finishing in Belgium. I'm actually carrying on into France, to Dunkirk, but that's not really part of the NSCR. (I am missing out Sweden by getting a ferry from Kristiansand to Hirtshals)
