This is a smart pen I purchased for 9800 yen during Black Friday in 2025! It can be used with anything that connects via Bluetooth, including iPads, PCs, Android tablets, iPhones, and more! I was using it as a companion for my iPad, but I'm selling it because I bought the official Apple Pencil and no longer need it. The writing feel and battery life are both excellent!! I've disinfected and cleaned it, but please refrain from purchasing if you are overly concerned about minor details. Instant purchase is OK! No returns accepted to prevent any issues! Thank you!
