- Initial Device Settings (for iPad/iOS users):
If you experience issues with writing or drawing on your iPad/iOS device (e.g., only swiping and tapping work), adjust the following settings:
- Go to Settings > Apple Pencil > Turn off Only Draw with Apple Pencil.
- Alternatively, go to Settings > Notes > Turn off Only Draw with Apple Pencil.
These settings ensure compatibility with third-party styluses. Other applications may also require similar adjustments.

- Cleaning: Wipe the stylus body and tips with a soft, dry cloth. Do not use abrasive cleaners or immerse the stylus in water.

Troubleshooting
- Stylus not writing/drawing on iPad/iOS (only swiping/tapping):
Refer to the "Initial Device Settings" in the Setup section. Ensure "Only Draw with Apple Pencil" is turned off in iPad/iOS Settings > Apple Pencil or Settings > Notes.

It instructs users to check iPad settings to turn off "Only Draw with Apple Pencil" and suggests checking pen tip tightness and power. A "No palm rejection" icon is also present.
- Stylus unresponsive or inconsistent:
- Check Power: Ensure the stylus is charged. If the battery is low, the pen will not function correctly.
- Check Pen Tip: The pen tip might be too tight or too loose. Try gently twisting the pen tip to ensure it is securely seated.
- Screen Protector Interference: If you are using a protective glass film on your device, it might affect the stylus's responsiveness due to thickness. We recommend a protective film of 3mm or less.
- No Palm Rejection:
This stylus does not support palm rejection. When using the stylus, avoid resting your palm on the screen to prevent unintended input.
- Not working with Chromebook/Windows:
This stylus is not compatible with Chromebook or Microsoft Windows System devices.
