This is an Apple wired keyboard with a US layout and a numeric keypad. I've been using a different keyboard and kept this one as a spare, but I don't seem to need it, so I'm putting it up for sale. I had no problems when I used it before. I connected it and tested it for this listing, and it seems to be working fine. As you can see in the photos, there is some dirt. Please purchase if you don't mind. I think US keyboards are not very common, so how about it if you're looking for one? - 2 USB ports
