Piano Line 8.5-inch Electronic Memo Pad Digital Memo Pad ◉ This 8.5-inch electronic memo pad is convenient for taking quick notes during lessons. ◉ It comes with a dedicated pen, and you can adjust the line thickness based on pressure, giving you the feel of a real pen. It's as easy to use as sticky notes, and the paperless aspect is a plus. ◉ Unnecessary notes can be easily erased with a single touch. On the other hand, the bottom has an "erase lock function," so you don't have to worry about accidentally deleting important notes. ◉ It's thin (0.5cm) and lightweight, making it easy to carry around. It's useful for recording lessons, as well as for drawing or as a message board. ◉ The battery can be replaced, allowing for long-term use. ※ Includes one CR2016 button battery (for testing) Brand new, unused. Convenient and very cute. I have multiple, so I'm selling them.
