So far I haven't heard any report of both Present Box and Decoration Material dropping in the same instance though. So while they are additional to ship drops, they may be mutually exclusive with each other.

Additional quest information:
 * Nanamin reports the additional rewards from the 16-quest level are a Mamiya and a Present Box.
 * Nekomahjong reports that completing the 32-quest level REMOVES the Decoration Material from your inventory. As if 30-fuel per material wasn't stingy enough.
