Thank you for viewing. This is the ELECOM gaming mouse M-DUX50. Operation has been confirmed. There is no box or other accessories. The underside of the mouse shows some signs of use, but I didn't play battle royale games. I used it for ARK for a while, and then switched to a wireless mouse, so I think the buttons haven't deteriorated much. Thank you.
