I ordered these to replace some that I had in pictures frames that were falling apart. The price was so good I couldn't resist. Only problem was that they didn't fit into all my frames. they were loose on some and to tight on a couple. My suggestion is if you are ordering these for frames you may want to measure how thick you need the picture back to be before ordering these to make sure they will work for you. Mostly they fit well and seem very sturdy.
