11x14 mat board with five 4x6 openings, perfect for displaying and highlighting up to five photos or paper artworks in a single frame. A mat board (passe-partout) is a cardboard sheet, typically with a centered opening, that creates space between the photo and the frame. It protects your artworks by preventing direct contact with the glass and provides a neat, professional presentation. This mat board is suitable only for paper-based works such as photographs, drawings, or prints, and should not be used with canvases.
