※ Requires a computer, tablet, etc. with a built-in Bluetooth adapter, or a separate Bluetooth adapter (sold separately). Please note that this is not a USB receiver type connection. Please check the official website for details. Operation has been confirmed on my home computer. I believe it can be used normally, but as it is a used item, I cannot guarantee the same click response as when it was new. Therefore, please refrain from purchasing if you are seeking perfection. There are minor scratches, but it is in relatively good condition. I will sell this to those who understand the above and agree to no claims, no returns. Mouse Management Number 38
