I used this mouse about 5 times after purchasing it, but it was a little too big for my hand, so I stopped using it and stored it away. There is some slight blackening on the white part on the front left (see photo 5), but otherwise, there are no noticeable scratches or stains, and it is clean. I have confirmed that it works without any problems when checking its operation before listing it. ◆ I will carefully protect it and ship it via Yu-Packet Plus. ※ Batteries are not included.
