This is an older wired Tabmate controller. I used it for about two years after purchasing it, but I switched to the wireless Tabmate when it came out, so it's been sitting in a closet. I confirmed that it works without any problems on the latest version of CLIP STUDIO (4.0). Since I used it frequently, there are signs of wear and tear on the controller itself, and the rubber on the stick is deteriorated and torn. There is also stickiness due to aging. Therefore, please refrain from purchasing if you are sensitive to these issues. There are no instructions or box.
