Power-on operation has not been confirmed. Pair Microphone Model Number: KA-HM-F1 Microphones: 2 Cords: 2 This item has been opened, but has been stored unused, so I am offering it for sale. The box is tattered due to aging, but the contents are in a clean condition. I think it can be used for karaoke practice, events, etc. [Retail Price] 19,800 yen Made by Chuo Denki Kogyo Co., Ltd. (CHUDEN) *Please understand that due to long-term storage, the box has deteriorated over time, and I have not been able to confirm the operation before listing due to lack of equipment. Please purchase with this in mind!
