A Folio Universitas or Folio Magi is an album-like book, in which the owner can store Famous Wizard Cards. While at Hogwarts School of Witchcraft and Wizardry, Harry Potter, Ronald Weasley, and Hermione Granger traded, found, or bought (from Fred and George Weasley's shop in Gryffindor Tower) cards, and then stored them here, where they could be observed.
