Store the active (digitizer) pen in the pen holder when not in use.
Avoid storing the pen vertically on its tip. It can damage the pen-to-digitizer function.
Keep the pen away from any liquid, because the pen contains electronic components that can be damaged when wet.
In certain environments, particles or debris can stick to the pen tip or the tablet display. Make sure you wipe off the pen with a soft cloth to avoid scratching the display.
