The gingerbread house comes with its own box (which unfolds and doubles as a building platform), a piping bag, icing sugar, as well as all the pieces to construct your house. Note, it does not include lollies. You do need one egg to complete the royal icing, but the instructions are included in the box.
Please take care when constructing or consuming and ensure that children are supervised. The gingerbread house kit contains small pieces (such as components for a chimney) which may present a choking hazard for children under 8.
