This is a Bluetooth keyboard from Elecom. I purchased it used on Mercari around March 2025, and it was almost unused. I am selling it because I no longer need it, as I have switched to a different keyboard. Please note that the outer box and batteries are not included. - Brand: ELECOM - Color: Black - Connectivity: Bluetooth - Features: Compact Design Thank you for looking. Connection type...Wireless (Bluetooth)
