I need story help! - Drarry

What would Draco get Harry for Christmas?
And vice versa?

It's not an "important" element to my story, but at the same time it is, and I have no idea what to put... So please, any ideas?
And it can't be ridiculous, like an IOU for a night of sex or something, something realistic, a book or scarf or... I don't know... And something Harry can explain away when people ask who it's off...

I was thinking a Slytherin scarf, but I think that's a little too obvious... I don't know, please help! I'm so amazingly stuck right now :')
