Description
About this set
In this set, the Room of Requirement becomes Neville Longbottom’s hideout inside Hogwarts Castle. The 202-piece build is full of little touches, like racks of old relics, two hammocks, a few benches, a chimney, plus a portrait of Harry and his friends. The room folds out for play, and Neville is included as a minifigure so he can settle right in.
Kids 8 and up who love the Hogwarts stories will have fun with it. Collectors will like that it folds to fit with the modular Hogwarts castle sets. It’s retiring, so new sealed copies are getting harder to find.
Highlights
- Neville Longbottom minifigure included
- Two hammocks, a chimney, benches and a portrait
