Harry Potter fans know that Hogwarts Castle always appears like a ruined building in the eyes of muggle people. And whether you are a Muggle or a Witch, we can now see this magnificent castle with the Omoshiroi Block memo pad. As each page was torn off and used, Hogwarts Castle would gradually appear along the back of the stack. When all the pages are out, a replica of the witch’s school is fully exposed, ready for you to display them on a table or shelf.
