Thank you for viewing. The product's appearance is generally clean, but there are noticeable scratches on the back, so it is rated as "Slightly scratched or dirty." After a light cleaning before listing, the operation has been confirmed. It works perfectly with both an AC adapter and batteries (photos 2 and 3). The listing includes only the amplifier unit, so you will need to provide your own batteries or adapter. Also, there is no outer box. The unit will be wrapped in waterproof vinyl, bubble-wrapped, and packed in a cardboard box with cushioning material for shipping. Shipping will be via Mercari's anonymous delivery service.
