Ideal for aspiring wizards, this kit contains code-making instructions, 16 sheets of notepaper, 16 envelopes, six postcards and two sheets of stickers. It allows individuals to communicate with other apprentices of Wizardology by using mysterious codes. “The OLOGY code-writing kits capitalize on the unrelenting popularity and demand for the bestselling children's book series. These are surefire hits in the toy market,” Tracy Miracle of Candlewick Press told TDmonthly. Launch date: August 2007.
