This is an Elecom Deft Pro. It doesn't have a box, just the main unit. I bought it, but it's almost unused, so I'm putting it up for sale. It's a USB-connected trackball mouse, characterized by its red ball. - Model: Trackball Mouse - Connection Type: USB connection - Color: Black - Ball Color: Red - Port: USB port - Function: Trackball function - Other: Slide-type cover on the bottom Thank you for looking.
