Marik, being the loving and very responsible brother that he is, has sent a birthday gift to his twin, and Xmas gifts to Malik and Isis. As well as an anonymous gift to Varon, but that one is just because he's a bastard. Bakura, Diabound and Ryou also got gifts, just because the Bakurae and Ishtars stick together and Bakura is, after all, Marik's not-a-boyfriend.
For Malik, there's a kit of hair dye. Lots of different colors, washes out after a couple of weeks, and it's wrapped up in white paper with a pattern of black music notes, tied with gold ribbons. That's his birthday gift.
Isis gets a box filled with tiny little bottles of various sorts of alcohol. You know the small kinds they sell in Europe in the check-out aisles? Those. They're each individually wrapped up in bubble wrap, and the box overall has a ivy-and-mistletoe print, with red ribbons tied around it. The same paper has been used to wrap the rest of the Xmas gifts which are as follows:
Malik -- Red leather waterproof gloves, and a card suggesting, If you build an obscene snowman, make the penis really small and stick up a sign saying 'Kaiba v4' to see what happens.
Ryou -- He got the same gloves in white, as well as a note saying, Go start a snowball fight with Malik. He needs the exercise.
Bakura -- Mistletoe dangling from a string attached to a stick. In other words, portable mistletoe. The card says, Come find me to use it., because Marik misses him more than he'll let on.
Diabound -- Weed. What else? And a charm for his daughter that looks like a bundle of leaves bound in thread, accompanied by a note explaining, The swamp witch said to hang it over her crib to give her good dreams. The weed'll do that for you.
As for Varon, he got a lot of special photos of Yami. No elaboration necessary.
