Thank you for viewing. [Brand New] [Specifications: 6 buttons with side buttons] You can use it immediately by simply plugging the receiver into the USB port. It doesn't have any special features, but it has the minimum necessary functions, so I think this is sufficient for everyday use. Unlike rechargeable mice, this one uses two commercially available AAA batteries, so you can use it for a long time. Description • Wireless Connection: Enjoy freedom of movement with a 2.4Ghz wireless connection, eliminating the need for cords and cables. • Ergonomic Design: The mouse is designed to fit comfortably in your hand, reducing strain and fatigue during extended use. • Universal Compatibility: This mouse is compatible with a variety of devices, including laptops, desktops, and game consoles. *It will be shipped by regular mail. If you wish for anonymous shipping, it will be an additional 250 yen due to the thickness of the product. Please let me know in the comments before you complete the purchase. Thank you.
