Mystery Swag

One of my favorite things to receive during Oscar season is mystery swag - unlabelled promotional items just to keep you thinking about a film. My favorite ever was two years ago when a black envelope from "Nina Sayers" arrived. There was nothing inside it but a few feathers. This week in a last minute rush of FYC booklets and animated film paraphenalia (Wreck-It Ralph hands, Brave bow & arrow, stuffed Frankenweenie -- guess which Oscar is up for grabs?) I received this little box in a totally unlabelled package, tied with a yellow bow...

But what do I unlock with it?
