Please check the photos and ask any questions you may have. Since I am not a professional, the operation has not been confirmed. Thank you. If a different product arrives than what is pictured, please be sure to contact me before completing the transaction. Basically, it will be a single item, so in most cases, I will not have a replacement. In that case, I will offer a refund or cancellation. I hope to have a pleasant transaction from start to finish, as this is a short-term interaction. If you have any questions about the product, please feel free to comment. I will respond promptly.
