This 25-pack of 10" Clear Print Mount Strips from Archival Methods is for prints larger than 20 x 24" which require more support than mounting corners can provide. The strips are applied along the print's bottom, top, and sides to provide even support for the artwork. Crystal clear polyester is archival, and safe to use next to artwork.
The strips are 10" long with a 1/2" channel-fold, and can be trimmed to accommodate borders as small as 1/8". Half inch double-sided tape is applied to the 2" polyester back, so that no adhesive touches the artwork.
