These patented frames are magnetic on one edge for changing the picture, and magnetic on the back to adhere to refrigerators, lockers, filing cabinets, etc. They also adapt to wall hanging by putting a saw-tooth hanger, which we provide, on the back magnets. They also smartly fit between 2 doors where framed pictures don't normally fit. Our same patented frame design (Patent No. 7,802,390) allows for easy picture changing. These measure 3.25" by 4.25" providing accommodation for a 2.25" x 3.25" wallet size picture, either portrait or landscape orientation when magnetic, portrait only when saw-tooth is used.
