These patented frames are magnetic on one edge for changing the picture, and magnetic on the back to accommodate the stand in either landscape or portrait orientation. Our same patented frame design (Patent No. 7,802,390) allows for easy picture changing. These measure 6.25" by 8.25" providing accommodation for a 4x6 picture (using an optional matting board) or a 5x7 without any matting. Please include a note if you desire a matting, and specify the color (black, beige, light blue, dark blue).
