Frames can be ordered with Clear Glass – Non Reflective Glass or Art Screen Acrylic. You might fined that clear glass & non-reflective may not be an option on larger frames, this is due to larger pieces of glass being more likely to break during shipping. Art acrylic is available for larger frames. We have been supplying glass to mail order all over the country for 20 years. Very rarely do we get any broken – but in the case that we do we can only refund you for this; unfortunately we cannot supply a sheet of glass via couriers. Sorry.
