Let the Sorting Hat Mug predict the Hogwarts House of the drinker. The Sorting Hat always takes into consideration which House you want, and in this case, Hufflepuff will have gained a wonderful new Wizard or Witch. Hand wash only. When a hot drink is added, see the heat magically change the plain Black mug into Hufflepuff's colours and reveal the Hufflepuff House Emblem. The House revealed is shown in the peelable sticker on each mug box (which otherwise are identical to each other). The sticker should be removed before gifting to the hopeful Wizard or Witch. Collect all 4 of Hogwarts Houses; Gryffindor, Ravenclaw, and Slytherin Mugs are also available and sold separately.
