Because Hogwarts castle looms so large in the imagination of fans all over the world, we made the new Building Cards set bigger than its predecessors - and packaged it with over 275 cards. Sturdy slot-to-slot construction means there is no need for glue or nails and the cards can be taken apart and reassembled over and over again. The instructions feature assembly hints, step-by-step illustrations and directions so simple even a Muggle could follow them. Also comes with a custom-molded Harry Potter figurine.
