Smart Keyboard Folio for Apple iPad, 11-inch, US version. I believe it's compatible with Pro and Air models, excluding the M4. As a left-handed user, I have a strong habit of using my pinky, and the "A" key is slightly worn, but all functions are fully operational. I purchased it from the Apple Store a year and a half ago and used it until February of this year. It's lightweight, making it convenient to carry around and use. Thank you for looking.
