Returning an item, what do you tell the rep what's in the box?

Hi! I haven't seen a post for this yet. I am curious to know what others responses may be when shipping an item back and the representative asks what the contents of the box is? I'm shipping a vibrator back and am just curious what you'd tell them? Also, if you would mention if it has a battery in it as this would raise some flags and other questions.
TIA!
