Chiba Lotte Marines These cards were distributed at a summer festival game held at ZOZO Marine Stadium. This is a set of 5 cards. The back of the cards contains a password for the M Collection, which expires on August 31st. Please be aware of this. If you purchase the cards by August 30th and would like it, I will send you a photo of the password in the comments. The cards were handed out at the stadium and brought home in a bag, so please understand that there may be some scratches or corner bends. Shipping will be via standard mail. Thank you for your understanding.
