Grafix - Double Tack Original - 6 sheet package - 9x12 - Grafix Double Tack Mounting Film is great for mounting drawings, photos, and much more. It requires no moisture, glue, heat, or activator. Save by buying large sheets and then cutting them to the size you need. It has a twin coating of permanent adhesive on two sides of thin film, sandwiched between two heavy release papers. Lift up one of the release sheets, apply the sticky side to the subject, and then remove the other release paper before applying to the surface.
