This particular menu cover fixing mechanism works in exactly the same way as a photo album. Frames are attached to the inside front and back of your menu covers so all you need to do is simply slot in your paper or card behind the acetate.
Extra sides to view can be added by simply sewing in more frames to the inside spine of the cover, or by using a wing and interscrew should you require them to be removable.
Metal corner protectors for the frames are also available upon request, with a colour choice of silver, gilt, bronze or black.
