This item is the "Meiji Kinoko no Yama Wireless Earphones." It was released as a limited edition of 3,500 units at the time. I have kept it unopened as a collector's item, but I am selling it because I have no opportunity to use it. Since it is an unopened item, the certificate and instruction manual are inside the box. However, I will only provide the item shown in the photos, so please understand this before purchasing. In addition, since the operation has not been confirmed, I will appropriately address any initial operational issues before evaluation. * Please refrain from inappropriate actions such as swapping the product or returning it damaged, as I have recorded the serial number. For safety, the serial number has been blurred. Thank you for your understanding. No price reduction.
