A variety of reflective surfaces in a metallised plastic format. Although the rigid mirror is certainly thicker than the thin mirror it is not exactly rigid - which is how we can sell it by the roll! We would recommend Display Mount to glue smaller areas and Flints Cyclorama Glue for larger areas. Care must be taken to ensure that the Cyclorama glue surface is smooth before applying the mirror. Rolling the wet glue with a damp short hair roller will assist.
