This item has come from a heating company liquidation and is not retail packed, it is in a bubble wrap bag and does not include the screen holder, which we believe can be purchased for around £10.  To the best of our knowledge this item is new and unused, if the buyer wishes to return this item ( in its original condition ) within 14 days this is not a problem if unhappy for any reason. 

Thanks for looking at our items, others being added daily.
