I purchased these items for the purpose of articles related to the Science ADV series. All items have some scratches and stains. I have only flipped through the contents, but I don't think there were any noticeable stains. Only the "Wolf TYPE" item does not include any bonus items. All other items are complete. The Nitroplus DVD case is torn, and the Comptiq drama CD seal is dirty. I have not checked the playback of the discs. The Famitsu DLC is unopened, but I don't know if it's still usable. There was no mention of an expiration date. I am an amateur, so I may have overlooked something. Please refrain from purchasing if you are looking for a pristine item. I will not sell items separately.
