I purchased an unused item that was only opened, so it is in a clean and pristine condition without any scratches. I have confirmed all the operation buttons in CLIP STUDIO PAINT. A product code is included, but its usability is uncertain, so please consider it a bonus if it works. • One-handed operation You can smoothly switch tools, undo, zoom, scroll, and perform other operations with your other hand without stopping your drawing. • Customizable You can assign any CLIP STUDIO PAINT shortcut to each button. You can customize it to suit your work style. • Bluetooth compatible & rechargeable Provides a comfortable wireless work environment. It is rechargeable via USB Type-C, eliminating the need for battery replacement. • Compact & lightweight design Ergonomic design that fits comfortably in your hand. Designed to reduce fatigue even during long hours of work. • Multi-platform support Compatible with Windows, macOS, iPad, and Android (Bluetooth connection required). Recommended environment: Devices with CLIP STUDIO PAINT Ver. 2.2.0 or later installed Bluetooth 4.2 or higher compatible devices
