Acrylic Designer Mirror is offered exclusively by Titan Mirror Company. Designer Mirrors have a higher-caliber backing compared to painted backs. Designer Mirror has a protective backing on the mirror that is metalized polyester which is far superior to painted backs, as it fuses to the acrylic when laser cut to seal out mositure. It makes the sheet much stronger, as it is now a layered product, like plywood. Designer Mirror sheets are great for you to custom laser cut into any size or shape.
