I purchased this keyboard about two years ago and used it at work, but I'm selling it because I bought a new one. There are no operational problems, and it works without issue. The cable connector is Micro USB Type-B, and it's a type that uses a USB receiver plugged into the PC, without Bluetooth functionality. - Type: Wireless - Layout: Japanese - Brand: iClever - Color: Black ※The images after the second one are reference images.
