I have 4 frames, $10 each. Real glass, size 28x22. Made of lightweight aluminum. I threw out the cardboard backing because it was old. They come with 9-12 clips on the back. They are not wired.
You could get some foam board or cardboard if you need a backing for a photograph. You could use the frames for canvases without the glass or you could just purchase the glass if you have a frame with broken glass.
Cash only. Pick up in Medford/Marlton
