PostCups are back for Christmas, with one-of-a-kind festive greetings for people tired of the same old store-bought Christmas cards. Each Christmas postcard has a drawing that's completed by coffee stains - so you can send some Christmas cheer via a coffee reindeer, Santa, snowman or snow globe (like the first edition of PostCups which was trending 9 months ago, see it here). Because each PostCup is completed by your coffee stains, every Christmas card is unique.
