The Patronus Charm is one of the most ancient of charms and appears in many accounts of early magic. Used to protect against Dementors. We all remember when Harry whipped out his wand and used this defensive charm to save a future version of himself while using the Time-Turner. This top has the famous Harry Patronum in white with the "Expecto Patronum" words at the bottom. Fitted for juniors sizing this tee will fit snug. Made of 100% cotton and tag-less for comfort.
