Bluetooth trackball mouse, featuring a red ball. - Brand: ELECOM - Model Name: bitra - Connectivity: Bluetooth - Included items: USB receiver, case - Ball color: Red - Shape: Trackball Thank you for viewing. It didn't quite fit my usage environment, so it's practically unused. Box and instruction manual included. As a bonus, I'll include the recommended Bluetooth adapter LBT-UAN05C2 (without the box).
