Bevelled Mount/Mat for Photo/Picture Frames. A mount is placed between the picture and the frame and provides a border between the two, creating a visual separation and emphasizing the artwork or photograph. It can also help to protect the artwork from damage by preventing it from touching the perspex front of the frame. All of our Mounts are acid-free and have a machine-cut bevelled edge. * Variety of sizes to choose from. * Mounts are bulk packed, and wrapped together, not individually.
