The advent calendar has a buildable surprise (and simple building instructions with pictures) behind each box.

Children will discover 6 LEGO Harry Potter minifigures new in September 2023, including the first-ever minifigure of Desiderius Dumbledore, plus 18 mini-models depicting the magic of the wizarding village of Hogsmeade. With models having to do with Inn The Three Broomsticks, Cafe Swine's Head, Zonko's Fop Warehouse and Zacharinus' Confectionery, the play possibilities increase as Christmas approaches.

The minifigures and buildable models in this festive Christmas Advent calendar for kids can be combined with other LEGO Harry Potter sets for even more creative play opportunities. The set is a magical Harry Potter gift for children and fans ages 7 and up.
