Ao no Hako (Blue Box) Volume 1-20 set. Thank you for viewing this item. I purchased these new and have kept them on a shelf after reading them once. I have confirmed that they are in relatively good condition. However, please understand that these are used items and only purchase if you are comfortable with that. No pets, non-smoking environment. Immediate purchase is welcome! Thank you. Ao no Hako (Blue Box) Volume 20
