Thank you for viewing! The product details are as stated in the title. Please check the condition in the photos. It may be difficult to see in the photos, but the outer box has a slight inward dent. The instruction manual has some wrinkles and rust on the staples. Overall, it's in good condition. The terminals have been cleaned, and the item has been tested and confirmed to work with my Retro Freak. The backup function is not guaranteed. This is a valuable item that cannot be replaced, so returns and refunds are not accepted. It will be shipped in a Takkyubin Compact dedicated box.
