Add a touch of Hogwarts magic to your everyday with these Loungefly Harry Potter Cosplay Mystery Mini Backpack Keychain Charms. Each blind-box charm is shaped like a tiny Loungefly mini backpack and celebrates an iconic element from the Wizarding World â from Hedwig the owl to the Hogwarts uniform and the crests of each house. Every charm comes individually wrapped, so you won't know which design you'll receive until you open it â making them perfect for collecting, gifting or swapping. Finished with applique and printed details and a gold-tone lobster clasp, they're ideal for clipping to your keys, bags or existing Loungefly pieces.
