Captain Underpants Most Epic 5 Book Set: The Captain Underpants Extra-Crunchy Book o' Fun, The Captain Underpants Extra-Crunchy Book o' Fun 2, The Adventures of Super Diaper Baby, Super Diaper Baby 2, The Adventures of Ook and Gluk Paperback – January 1, 2013

While the 5 book set came sealed, the extra crunchy book o' fun was used! Half of the stickers were gone and most of the activities were filled in when we first opened it! How can this seller claim to sell a new product when it is clearly used?! And to re-seal the 5 book set is even more deceitful! My 9-year old was disappointed, but was even more upset that we may have to return all 5 books to replace the one so I decided to keep them all. Shameful!
