when do warhammer christmas boxes come out

Unfortunately, Warhammer Christmas boxes do not exist. The Warhammer series is a collection of tabletop games and miniatures, and it is not associated with any specific holiday or event. However, there are many other tabletop games that do offer seasonal boxes and products, such as Dungeons and Dragons and Pathfinder. These boxes often include themed accessories and supplements, but they are not always tied to a specific holiday.
