Note about the 1/8" mirror (metallic) acrylic option ONLY: These sheets will have your desired pattern on one side and PatternPly® Solid BLACK on the back side. The image itself will be transparent, enabling the metallic layer to shine through. The overall sheet is opaque, however. Unlike our other acrylic offerings, the mirrored acrylic cores use an extruded acrylic. All the other acrylic cores are cast acrylic.
