 * The inventory icon for the wrapped item is a wrapped package in one of six color combinations.

Warning
A common scam was to wrap up a worthless item and COD it to a player, hoping that they would accept and send back a large amount of gold for a poor quality item. This was fixed in a patch so players cannot mail wrapped items anymore. However, scammers now just send the wrapping paper itself now.
