Navigate your way through Hogwarts with the Marauder's Map. Activate the map by speaking the phrase, "I Solemnly Swear That I Am up to No Good™." The blank piece of parchment paper then becomes a very detailed map of Hogwarts. This magical phrase is written on this tote bag along with the footprints on those walking around in the map. Wipes clean with a damp cloth. 14.75"W x 14.75"H cotton/poly.
