Thank you for viewing. Includes the 3Dconnexion SpaceMouse Wireless and universal receiver. Everything in the photos is included. I used it once or twice after purchasing it, but I couldn't get used to it and stored it away. When I opened the carrying case to inspect the unit for sale, the rubber on the operation part of the main unit had become sticky due to aging. Operation has been confirmed. - 3Dconnexion SpaceMouse Wireless (Micro USB) - 3Dconnexion Universal 2.4 GHz USB Receiver - Carrying case Purchase date: 2020 - Brand: 3Dconnexion - Connectivity technology: Wireless - Color: Black/Silver
