OK, Harry Potter fan, point your wand at the Marauder's Map (if you have it) and take the oath: "I Solemnly Swear That I Am Up To No Good." Now, hang this Harry Potter Solemnly Swear Lighted Sign bearing these words on your wall! Crafted with a quality beveled mirror and a wooden frame, it measures roughly 6 3/8-inches high x 6 3/8-inches wide and includes a 6-hour on/off timer. Gallopin' Gorgons, that's cool! Requires 3x "AA" batteries, not included.
