Yes, we use quality glass for our frame sizes 3 letters through 9 letters. For our large frames (10, 11, and 12 letters) we may substitute the glass for plexiglass in order to provide safer shipping and to better assure that the artwork arrives with no damage. The plexiglass also makes the artwork lighter, allowing you to handle it and hang it much easier. All of the Wedding/Event frames use plexi glass in order to ensure safe shipping and handling.
