Xiaomi LCD Writing Tablet 13.5"

Pressure-sensitive writing: The thickness of the lines changes depending on the pressure applied with the pen or your finger.
Magnetic pen: The lightweight pen (only 7 grams) is made of a smooth and durable "super steel" polymer. It magnetically attaches to the side of the tablet for safe and convenient storage.
One-touch screen cleaning: A single press of a button instantly cleans the entire screen. The color version also has a "Holi sensor" that allows you to clean the screen by touching the top of the pen to the tablet.
Screen lock button: This feature prevents your notes or drawings from being accidentally erased.
Low power consumption: The zero-power LCD screen uses only a small amount of power when the screen is cleaned. A single button battery (CR2025) can last up to 365 days if the screen is cleaned 100 times a day.
