The Marauders Map is a special map showing the detailed plan of the magic school of Hogwarts with its surroundings, as well as the location of everyone who is at this particular moment in this area. In order not to get on the map, you need to hide in the Room of Requirement.
Without a mysterious map, Harry Potter's story would be less exciting. It should be noted, when the map is hidden, it cannot be distinguished from a usual piece of parchment. Such a valuable object was given to Harry Potter by the Weasley twins, after first taking it from the cabinet of Filch. Since the book does not have a detailed description of the map, artists and fans of the works of J.K. Rowling had to recreate it literally bit by bit.
Would you want the Marauders' map to be always on your desktop, and if you wish, you could take it anywhere with you? Order a unique case for the laptop; in appearance it is absolutely identical to The Marauders map! Your laptop in such a cover will look stylish, trendy, respectable, and mysterious. Just do not be surprised if any fan of Harry Potter touches it with something that looks like a magic wand, and swears that he is planning a prank.
