I believe these are made of plexiglass or Polycarbonate or acrylic. They appear to have been cut too fit a specific area since the cuts along the 2 shorter sides are not perfectly straight. These are old, they are not in perfect condition.EXACTY as shown - please look at edges carefully as I stated they have been cut. Crack in the one as shown - Non smoking household - I do not know where these came from.
