Thank you for viewing. This is an EWI4000sw. Battery operation and sound output have been confirmed. I purchased this item new. I used it once or twice and then stored it in a dark place. There are minor scratches, so please refer to the images. Part of the instruction manual is torn. It's an old item, so there may be some age-related deterioration. The items in the photos are all that are included. I haven't used it much, but it is still a used item. Please understand. I will ship it in the original outer box shown in the photos. Please purchase if you understand. I will include two instruction books as a bonus. ◎Overview◎ EWI4000sw body Outer box Attached strap Mouthpiece cover Two instruction manuals Preset program list Two bonus instruction books
