The perfect replacement for traditional whiteboards: an ink/chalk-free electronic writing board with a large 15-inch writing/drawing area. It's an incredibly practical office tool for quick meetings, short presentations, and brainstorming sessions. Featuring the latest highly sensitive LCD panel, it emits no radiation and has no dazzling backlight, reflecting natural light instead. As a digital tablet, it requires no ink or chemical pigments, making it completely harmless to your eyes and skin. Write and draw directly on the LCD screen with the included stylus or other suitable objects, even your fingernails. A simple press of the button at the bottom clears everything from the screen. This drawing tablet also features a screen lock key to save your work from accidental deletion. This erasable and reusable digital tablet is powered by 1x replaceable CR2025 button battery (included). One battery enables up to 100,000 erases, saving you paper and ink, and reducing your office/home expenses. Warm tips: 1. Avoid sharp objects scratching the screen; 2. Do not get the board wet; 3. Turn off the screen lock before erasing.
