Xiaomi LCD Writing Tablet 13.5"

Pressure-sensitive writing: The thickness of the lines changes depending on the pressure applied with the stylus or your finger.
Magnetic stylus: The lightweight stylus (only 7g) is made of a smooth and durable "super-steel" polymer. It attaches magnetically to the side of the tablet for secure and convenient storage.
One-tap clear screen: A single press of a button instantly clears the entire screen. The color edition also features a "Hall sensor" that allows the screen to be cleared by tapping the top of the pen to the tablet.
Screen lock button: This feature prevents accidental erasure of your notes or drawings.
Low power consumption: The zero-power LCD screen only uses a small amount of energy when the screen is cleared. The single button cell battery (CR2025) can last up to 365 days if the screen is cleared 100 times per day.
