This is a Harry Potter themed travel bag that was exclusive to the Wizarding World crate from Loot Crate.  The clear vinyl outer bag has the wand motion for the spell Revelio on it, and is perfect to put small items in to get through airport security.  The inner bag has the Slytherin snake logo on it.  The set is new, never used, and was only even opened to take pictures.  Tag is still attached.  Check out my other listings to see the Gryffindor version of the bag.
