Logitech M650 Wireless Mouse and Keyboard Set Both were used with Bluetooth connection. - Brand: Logitech - Model: M650 - Connection Type: Bluetooth. USB also included. - Brand: Elecom - Model: TK-FBM120 - Connection Type: Bluetooth. No USB. There are no particularly large scratches, but there is some wear and tear. I had no problems using them, but they are used items, so please refrain from purchasing if you are sensitive to such things. Thank you for looking.
