Description
About this set
Hogwarts Castle: Potions Class is a 397-piece Harry Potter set that recreates Professor Snape’s dungeon classroom. The room opens out so it’s easy to play in, and it’s full of small details, like a blackboard with potion instructions, bottles of ingredients to stir into the cauldron and other classroom equipment. Two of the 14 collectible Hogwarts portraits hang on display.
Snape is joined by Seamus Finnigan, Pansy Parkinson and Hermione Granger as minifigures. It’s rated 8 and up and is a good starting point for new fans, while also linking with the other modular Hogwarts Castle sets. The set is retired, so sealed copies get scarcer over time.
Highlights
- Dungeon classroom that opens up for play
- Blackboard with potion instructions and a cauldron
- Bottles of potion ingredient elements
- Snape, Seamus Finnigan, Pansy Parkinson and Hermione as minifigures
- Connects with other modular Hogwarts Castle sets
