Thank you for viewing! This is an offering for an ELECOM wireless mouse with a red trackball, an 8-button trackball mouse for comfortable operation. I used it once, but the center ball didn't suit me, so I put it back in the original box and stored it. It's in almost-new condition, but since it has been used once, please refrain from purchasing if you are concerned about the details. It comes with a receiver, and I will include two new batteries. I plan to ship via Takkyubin (Yamato Transport) in a 60-size box. To ensure quick shipping, it is already packaged, so please understand that I may not be able to accept requests for additional images. - Brand: ELECOM - Model: HUGE - Color: Black/Red - Type: Trackball - Connectivity: Wireless - Number of Buttons: 8 - Supported OS: Windows/Mac - Power: AA batteries (2 new batteries included)
