To all DF members -- a nice card and a badge with "Defense Force" emblazoned upon it. You are not required to wear it!
To literally everyone else Suzaku has ever spoken to -- a nice card. He had a hand-cramp the day after from all the "Merry Christmas"'s. He has sort of formal-looking handwriting in Britannian, even though his Japanese is scrawly. So enjoy the script!
Gifts are given in person except where otherwise noted -- cards delivered through the mail!
