Thank you for viewing. This is a used, working Surface Type Cover in black, a Japanese keyboard, and is the genuine Model 1840. Operation confirmed. Compatible models: Surface Go 1/2/3 Although it is a used, working product, there is little staining. I think it's in pretty good condition overall, but it is a used item, so please check the images and consider purchasing only if you understand. No comments, instant purchase OK. Thank you very much.
