I believe it's in good condition as it's only been used a few times. There is a dent on the outer box. All included accessories are shown in the photos. Please check the images for the condition as well. I received this from an acquaintance, but I'm not very tech-savvy, so I couldn't use it. Therefore, I am selling it. I don't know the detailed specifications. Please purchase only if you can determine them from the photos and the instruction manual, etc. Shipping method may be changed to Yu-Yu Mercari delivery. - Model: All-in-One Aluminum Keyboard KD-K2 - Color: Space Gray
