I am selling this item because I haven't used it much since I bought it, as I am not very familiar with computers and the like. Since the operation has not been confirmed, it will be treated as junk. Please understand that this item has been stored at home. If a product different from the photos arrives, please be sure to contact me before completing the transaction. Basically, this is a single item, so in most cases, I will not have a replacement. In such cases, I will offer a refund or cancellation. I hope to have a pleasant transaction from start to finish, even though our interaction will be brief. If you have any questions about the product, please feel free to comment. I will respond promptly.
