Custom-framed and protected by anti-reflective glass.
Anti-reflective glass eliminates annoying reflections on the glass surface. The anti-reflection treatment carried out by depositing interferential multi-layers with metal oxides on both sides results in an 89% reduction in reflection.
This perfectly COLORLESS glass also offers the advantage of restoring the colors of the protected work in a natural way and it protects from radiation ULTRA-VIOLET, which accelerates the aging process in photosynthesis.
