The Hogwarts School of Witchcraft and Wizardry is the place where young wizards and witches go to learn the mysteries of magic. The students are divided into four houses; Slytherin, Gryffindor, Ravenclaw, and Hufflepuff. This charcoal heather adult tee features the classic Hogwarts School Crest. It is made of 50% Cotton and 50% Polyester. This is a great shirt, and it is perfect for fans of the magical Harry Potter films and books. Makes a great gift too.
