This is the Logitech MX KEYS wireless keyboard. I purchased it in 2021 and used it for about three years, but it has been stored at home for the past year. The 7 keycap is detached, and the tabs are broken. The key on the main body could be pressed, but I will include the keycap, so I hope you can repair it and use it. I think a small internal part has come off, as there is a rattling sound. There are scratches overall, but the operation was not a problem. User settings have been initialized. The USB receiver is not included. Please connect via your own USB receiver or Bluetooth.
