This is a late-model Apple Mighty Mouse Wireless (with white side squeeze buttons). It uses two AA batteries. I bought this new and used it, but I haven't used it in recent years and it has been stored at home. I'm selling it because I don't plan to use it in the future. I checked the operation before listing it, and confirmed that it works normally. There are some scratches from use, but I think the condition is good. However, since this is an older product, I've set the condition to "Slightly scratched or dirty." Please check the photos for the condition. Also, the lens cover for turning the mouse on is a bit stiff. Please be aware of this. - Brand: Apple - Model: Wireless Mouse - Battery Type: 2 AA batteries - Color: White - Connectivity: Wireless
