This is a small frame that fits photo size 3" x 3", the opening size at the widest part is 2 3/4" x 2 3/4".
This frame was obviously cracked at some time on the back side, it has been firmly glued and does now show from the front at all. The opening is quite narrow, so will not accommodate glass -- it will accommodate a small photo and polystyrene which will be included.
The outside measurement of the frame is 4" x 5 1/2". Frame is sold as is.
