ARCHIVAL MOUNTING CORNERS for photographs and art on paper
Archival mounting corners are used to securely hold photos and artwork to the backing board under window mats. The corners are made of 100% crystal clear safe polypropylene. Polypropylene is softer than polyester and is more pliable making it safer to use. They do not contain harmful PVC.
The pressure sensitive, non-yellowing acrylic adhesive holds the corners in place, is acid-free, and does not come in contact with the artwork.
