The Harry Potter Self Stir Mug is a work of magic (without having to master the Wingardium Levious charm!). With the push of the button this mug will stir itself taking away the need for a spoon
- they're for muggles anyway! The Harry Potter Self Stir Mug is embossed with the Hogwarts Crest in gold metallic. Requires 3 x AAA batteries (not included).
