This is my late husband's collection. There are 12 items in total, including 11 normal types and 1 secret type. They were opened and stored in PP bags for 20 years. This collection has never been displayed. The mini-books and outer boxes are also included. However, please consider these items as used, as they have been stored at home by an amateur. Please refrain from purchasing if you are concerned about minor details. Individual sales are not available. I will respond to any questions promptly.
