How do you prepare a package of sending a big box of Wii Rock Band through the post office? - wii wrapping paper

Selling my Wii Rock Band (guitar, drums and microphone) on Amazon.com. If I sell, I do not know, like going to prepare for the post. Should I strip the box or should I wrap it around with paper? Note: I've never been a big package sent through the mail. Suggestions thank you.
