8x10 mat board with two 4x6 openings, ideal for displaying and highlighting two photos or paper artworks in a frame. A mat board (passe-partout) is a cardboard sheet, typically with an opening in the center, that creates space between the photo and the frame. It protects your artwork by preventing direct contact with the glass while adding an elegant touch to your presentation. This model is suitable only for paper-based works such as photographs, drawings, or prints, and should not be used with canvases.
