Thank you very much for viewing. This is a Neptune-type tape. One channel contains one-way broadcasting. It's from the Hasuike to Yudanaka line. I am selling it to organize my collection. I did a light playback check when I obtained it, but I do not guarantee its current operation. We cannot accept returns or refunds if it cannot be played back or if there are issues with the sound quality. There are scratches and stains. Please refrain from purchasing if you are looking for a pristine item or if you are very particular. Please understand that this is a used/surplus item before purchasing. Also, please refrain from excessive price negotiations. Regarding shipping, we plan to use Rakuraku Mercari Delivery. Please note that shipping may be delayed due to work or other circumstances. Please let me know if you have any other questions. If you would like to purchase multiple items currently listed, please let me know. We can offer a discount on the shipping cost. However, we cannot negotiate specific amounts. Thank you for your understanding.
