Keychron K1SE Mechanical Keyboard, tenkeyless, Bluetooth and USB connection compatible, gray color. - Model Name: K1SE - Color: Gray - Connectivity: Bluetooth / USB - Brand: Keychron Thank you for viewing. - Can be used wired or wireless! - Low profile, so it's shallow and easy to type on! - Red switches, so there's no clicking sound, and a light key feel! I used it for about a year, but I'm selling it because I switched to another keyboard. Fully functional. I will pack it in its original box and ship it. Immediate purchase is also welcome. Thank you!
