BUFFALO wireless keyboard BSKBW100BK, with USB receiver and instruction manual. - Brand: BUFFALO - Model: BSKBW100BK - Connectivity: Wireless - Manual: With instruction manual - Accessories: USB receiver Thank you for viewing. I purchased this for in-game chat and used it for about a year. After I stopped using it, I stored it in a dark place, wrapped in plastic. There may be some fine dust in the gaps between the keys, but there are no noticeable scratches or stains.
