Hi, for sale is a Used Sony VAIO Wireless Keyboard VPG-WKB5US with Cover For Sony AIO VAIO System.  This Keyboard is wireless and previously connected to a Sony Vaio all in one system - there is NO dongle included as I think it was set up to work with certain systems so please make sure this is compatible with your system before you purchase.  There is normal wear but everything functions.  This works on 4 AA Batteries, not included.
