|Augusta Longbottom's handbag|
This handbag belonged to Augusta Longbottom. It is red and has a mousetrap inside. According to Neville Longbottom, his grandfather put a Fanged gerbil in her handbag as a practical joke in 1947. Ever since then, she has kept a mousetrap inside of it permanently. As that was mentioned in The Queen's Handbag , the canonicity of that is deemed uncertain.
