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 and it's been sitting around. I started it up again recently, and it worked normally. I checked all the buttons by setting them up in Tabmate, and all the buttons responded. Batteries are not included. To prevent any issues, I will not accept any questions, cancellations, claims, or returns after purchase. Please refrain from purchasing if you are overly concerned about details.
