This is a set of 4 books. It includes the Erika Ikuta Graduation Memorial Photobook, the Neru Nagahama photobook, and 2 magazines related to Nogizaka. I can also sell them individually, so please feel free to consult in the comments. Basically, photobooks are sold for 666 yen each. Magazines are sold for 444 yen each. The condition is as shown in the photos, with some noticeable warping, so I've marked it as "Used - with scratches and stains." Thank you for looking.
