This is a fully functioning wireless keyboard complete with the necessary USB plug.
It also has the wireless mouse it came with but I dropped this and it does not work. The mouse may be mendable but I cannot know that and don't have the skill myself to try. The keyboard works perfectly well on its own whether you want to take the mouse and give it a go or not.
