As Jeremy noted, you can ship in a box that has stuff written on it. The only problem you will run into is if you ship something through the USPS and it says something like "Hazardous Materials" or something like that written on it. You can still use the box in those cases but you just need to mark out those words with a black marker.
The main thing to ensure when using any box is to make the address label pretty obvious. Other than that, it doesn't matter what kind of box you use.
Quoting Mr. Harmon: Sure, but do not ship any Old Amazons in a book box.
I could add, "old Amazons never die; they just fade away." And that's fortunate for what could be the natural result: medical schools don't graduate that many plastic surgeons...
We get Amazon boxes in the mail all the time. Don't make the mistake of getting Amazon Prime. Free second day shipping on almost everything is not good for the pocket book.
