Dell ergonomic wired keyboard Model #SK-6000. It's in used condition and it has some wear. The keys are all responsive. It has a scuff on the top-right corner. The cable has some wear but looks good with no tears. The pins in the connector look good. I don't have a computer with this connection anymore so i can't test it. If you're not satisfied then you can return it for a refund. Thanks for looking!
