Black wireless mouse with Bluetooth connectivity and Silent Touch technology. I accidentally purchased the receiver-less type and was unable to use it with the PC I intended to use it with, so I am listing it for sale. The box has been opened and is slightly crushed, and the batteries have been inserted, but the mouse has not been used. - Brand: logi - Model: Bluetooth Mouse - Features: Silent Touch technology - Model Number: M240 - Supported OS: Windows, macOS, Chrome OS, Linux - Color: Black Thank you for looking.
