Operating Instructions
Palm Rejection
The stylus features palm rejection technology, allowing you to rest your hand comfortably on the iPad screen while writing or drawing without causing unintended marks or actions. This eliminates the need for special gloves.

Tilt Sensitivity
The stylus supports tilt sensitivity, enabling you to vary the thickness of lines by changing the angle at which you hold the pen against the screen. This feature is useful for sketching, shading, and creating dynamic strokes.

This diagram visually explains the tilt sensitivity feature, showing how holding the stylus at different angles (15°, 30°, 60°) results in lines of varying thickness, enhancing creative control.
Magnetic Attachment
The stylus features a built-in magnet for convenient attachment to the side of compatible iPad models, including the iPad 10th Generation. This design aids in portability and helps prevent loss.

Stylus Not Working After Powering On

- Forget Apple Pencil (if previously paired): Go to Settings > Bluetooth > Locate Apple Pencil in "My Devices" > Tap the "i" icon next to it > Select "Forget This Device".
