This is a Logitech PS/2 ball mouse. While some parts have faded and yellowed considerably, there are no noticeable scratches. I don't have a PC with a PS/2 port, so I haven't been able to confirm its operation. Please be aware of this. Also, to reduce shipping costs, the packaging will be simple, and it will be shipped via Yu-Packet Post. If you prefer more robust packaging, please comment. I will ship via Rakuraku Mercari Bin for 599 yen. - Connection type: PS/2 - Color: Gray - Wheel: Yes - Number of buttons: 3 (left button, right button, wheel button) - Size (approx.): Width 6cm x Depth 12cm x Height 3.7cm
