The frames were not of the quality I was expecting, especially for the money I paid. You present yourself as providing a premium product. 1) The inserts/mounts/backing board on one frame are if anything slightly too small for the wooden frame itself, whilst on the second frame they are too large - the plastic cannot sit flush against the front of the frame because it is too tight. 2) One piece of acid-free paper backing, for which I paid extra, seems to be two shades, as though it's from the end of a roll or otherwise poor quality. 3) The packaging included sticky tape, which was stuck straight onto the frame - this could not be removed without damaging the mdf backing. 4) One of the frames has a hairline crack several inches long.
