CLIP STUDIO PAINT One-Handed Device This is the version that only works on PC. I bought it used and was using it. I switched to a different device, so I haven't been using this one. I turned it on again recently, and it worked normally. I checked all the buttons in the Tabmate settings, and they all responded. Batteries are not included. To prevent any problems, I will not accept any questions, cancellations, claims, or returns after purchase. Please refrain from purchasing if you are a highly sensitive person.
