I bought this a few years ago to use for gaming, but I switched to the G Pro that came out later, so I haven't used it much. Operation has been confirmed. *I don't think there are any noticeable stains, but I have wiped it down just in case. The box is missing, but the cable, dongle, etc. are still usable, so I will send them all together. Please note that cancellations after purchase are not accepted. Price negotiations are also possible. If you have any questions, please feel free to comment. Wireless gaming mouse with 11 buttons and RGB lighting. - Brand: Logitech - Model: G502 LIGHTSPEED - Number of buttons: 11 - Connection type: Wireless - Color: Black - LED light: RGB
